Congressional Crypto Investigations After the 2026 Midterms: Subpoenas, Insider Trading, and Defense
On September 28, 2026, Reuters reported that Democrats plan to investigate Trump family business deals if they win either chamber of Congress in November. Representative Jamie Raskin and Senator Richard Blumenthal identified Trump-linked crypto firms and 1789 Capital, Donald Trump Jr.'s venture capital firm, as areas of particular interest. Both said no final target list exists. Staff told Reuters that probes could begin as early as February 2027.
On September 15, 2026, the Senate voted 49 to 50 on the motion to proceed to the Digital Asset Market Clarity Act. The motion needed 60 votes. Democrats objected that the bill's ethics provisions did not stop the President and other officials from profiting from crypto ventures. The Hill has since reported that disputes over Trump family crypto interests derailed the bipartisan negotiations.
Overview: Congressional Crypto Investigations and Current Enforcement Priorities
A committee majority controls subpoenas, staff budgets, and the hearing calendar. Blumenthal is in line to chair the Senate's lead investigations panel and told Reuters that Democrats will use their subpoena power. Raskin, who could chair House Judiciary, said Democrats will need to question Jared Kushner about deals with Saudi Arabia, Qatar, and the United Arab Emirates.
Democrats also intend to examine the administration's crypto enforcement decisions. In April 2025, the Deputy Attorney General's memorandum titled "Ending Regulation by Prosecution" narrowed the Justice Department's crypto enforcement priorities. A congressional majority cannot direct prosecutors. It can compel testimony about how prosecutors and regulators made their decisions.
Reuters reported that firms tied to the Trump family have hired lawyers for internal audits and retained crisis communications firms.
Congress cannot indict anyone. It can compel documents and sworn testimony and publish the results. Prosecutors, regulators, state attorneys general, and private plaintiffs can use that record for years. A false statement to a congressional committee is a federal felony with a five-year limitations period. That period runs past the end of the current administration.
Which Congressional Committees Would Investigate Crypto
Control of one chamber is enough to issue subpoenas, hold hearings, and send criminal referrals. Control of both adds coordination and a Senate-only enforcement statute. Seven committees are positioned to lead.
House Committee on Oversight and Government Reform
Oversight has the broadest investigative jurisdiction in the House. Its chair can issue subpoenas and order staff depositions. In 2019, Oversight subpoenaed President Trump's accounting firm for his financial records, which led to Trump v. Mazars USA, LLP, 591 U.S. 848 (2020), the Supreme Court's leading modern decision on congressional subpoenas for private financial information. A Democratic Oversight Committee would likely examine World Liberty Financial, its USD1 stablecoin, and transactions between Trump-linked ventures and foreign investors.
House Judiciary Committee
Judiciary oversees the Justice Department and the pardon power. Raskin, the ranking Democrat, is the likely chair. Its crypto agenda would include the October 2025 pardon of Binance founder Changpeng Zhao, the 2025 changes to DOJ crypto enforcement, and any lobbying that preceded pardons or case dismissals.
House Financial Services Committee
Financial Services oversees the SEC, banking regulators, and the Bank Secrecy Act. Ranking member Maxine Waters has pressed for scrutiny of the President's crypto holdings. The committee would examine stablecoin supervision under the GENIUS Act, SEC dismissals of crypto enforcement actions, and anti-money laundering controls at exchanges and issuers.
House Permanent Select Committee on Intelligence
The Intelligence Committee joined the 2019 Deutsche Bank subpoenas litigated alongside Mazars. Its focus here would be foreign influence. In 2025, World Liberty Financial announced that Emirati firm MGX would use USD1 to complete a $2 billion investment in Binance. Senators Jeff Merkley and Elizabeth Warren sought a federal inquiry into that transaction as a possible channel for foreign influence.
Senate Permanent Subcommittee on Investigations
PSI is the Senate's chief investigative body. Its charter expressly covers investment fraud schemes, commodity and securities fraud, computer fraud, and the use of offshore banking to carry out criminal objectives. Blumenthal is the ranking member and the presumptive chair. PSI has a long record of bipartisan staff reports on money laundering through global banks, and prosecutors have used those reports to build cases.
Senate Banking Committee
Senator Elizabeth Warren is the ranking Democrat on Banking and a leading critic of the President's crypto ventures. A Warren-led committee would focus on stablecoin reserves, bank and exchange compliance, and the ethics provisions that stalled the Clarity Act.
Senate Finance Committee
Finance has jurisdiction over tax and Treasury. Ranking member Ron Wyden has pressed for stronger crypto tax enforcement. Finance, like House Ways and Means, can obtain tax returns under 26 U.S.C. § 6103(f), an authority other committees lack. Token sales, memecoin proceeds, and foreign payments to Trump-linked entities all raise tax questions.
One Chamber or Both
The two chambers enforce subpoenas differently. A House committee facing a defiant witness can refer the matter for criminal contempt under 2 U.S.C. § 192 and § 194. The U.S. Attorney decides whether to present the case to a grand jury, and a Trump-appointed U.S. Attorney is unlikely to prosecute contempt arising from an investigation of the President's family. The House can also sue to enforce a subpoena, but that litigation has historically taken years.
Under 28 U.S.C. § 1365, the Senate can file a civil action in federal court in Washington to enforce a subpoena against a private person or company. A witness who disobeys the resulting court order faces contempt of court without any action by prosecutors. For private crypto executives and companies, a Democratic Senate presents the greater compulsion risk.
The Issues Congress Would Investigate
Each likely investigation asks whether money reached the President's family from people who wanted, or later received, government action. Four lines of inquiry follow. A fifth, trading on inside information, is addressed in the next section because it is the most likely to produce criminal referrals.
Trump Family Crypto Ventures and Their Counterparties
Reuters reported that the Trump family expanded into crypto, drones, artificial intelligence, and prediction markets over the past two years. Committees will map who invested in, bought tokens from, or partnered with World Liberty Financial, 1789 Capital, and related ventures. They will ask where the money came from, what the investor received, and whether any government action followed.
Pardons, Case Dismissals, and Enforcement Policy
The Zhao pardon, SEC dismissals of pending crypto cases, and the Justice Department's 2025 policy shift will draw scrutiny. Committees are not bound by criminal definitions, but prosecutors are. Any charge of bribery or an illegal gratuity under 18 U.S.C. § 201 that grows out of a referral must satisfy the "official act" limits of McDonnell v. United States, 579 U.S. 550 (2016). Close timing between a payment and a government decision is circumstantial evidence. Prosecutors must still prove the required link to a specific official act.
Stablecoins, Anti-Money Laundering, and Sanctions
USD1 is a dollar-backed stablecoin. Its issuer and the exchanges that carry it have compliance obligations under the Bank Secrecy Act and, as its rules take effect, the GENIUS Act. Committees will request customer due diligence files, sanctions screening records, and transaction data. They can also seek financial intelligence from Treasury. House Oversight obtained access to suspicious activity reports in its 2023 investigation of Biden family finances, and Democrats will cite that precedent.
Donor and Investor Access
Reuters reported that corporate donors to the White House ballroom project are expected to be among the first targets. Crypto token holders who received access to the President will face the same questions. Access alone is not a crime. A record showing access paired with a specific official benefit is the kind of record that produces referrals.
Insider Trading and Market Manipulation: The Likely Referral Theories
Trading cases are the most likely source of criminal referrals from a crypto investigation. Blockchain transactions are public and timestamped. Exchange and prediction market records show who traded, when, and how much. Committee staff can line up those records against the dates of executive orders, token launches, listings, and policy announcements without anyone's cooperation.
What Committees Will Look For
Staff will look for wallets funded shortly before an announcement, positions opened in the days before a government action, coordinated token sales by insiders, and transfers that route proceeds through new accounts or offshore platforms. Prediction markets are part of the inquiry. Donald Trump Jr. advises both Polymarket and Kalshi. In May 2026, House Oversight Chair James Comer sought internal records from both platforms over concerns that government employees were trading on nonpublic information. A Democratic majority would inherit that inquiry and widen it.
The Legal Theories
Securities insider trading. Trading a security on material nonpublic information in breach of a duty violates Section 10(b) of the Securities Exchange Act under the misappropriation theory. United States v. O'Hagan, 521 U.S. 642 (1997). The STOCK Act of 2012 confirms that members of Congress and executive branch employees owe a duty of trust and confidence with respect to nonpublic information derived from their positions. The theory applies only if the token is a security, and the current SEC has retreated from treating most tokens as securities.
Trading on government information in commodity markets. The Commodity Exchange Act bars trading commodity futures, options, and swaps on nonpublic information obtained from a federal agency or employee. 7 U.S.C. § 6c(a)(4). On April 23, 2026, federal prosecutors and the CFTC used that provision for the first time. They charged an active-duty Army soldier with using classified information about the January 2026 operation against Venezuelan President Nicolás Maduro to place Polymarket bets. The CFTC's parallel complaint treats event contracts as swaps within its jurisdiction.
Fraud-based misappropriation. CFTC Rule 180.1 reaches fraud in connection with any commodity, including spot bitcoin and ether and event contracts. In May 2026, prosecutors and the CFTC used it and the wire fraud statute against a Google engineer accused of making more than $1.2 million on Polymarket with confidential company data. The Congressional Research Service has analyzed how insider trading law applies to prediction markets and the pending bills that would extend it.
Wire fraud. Prosecutors use wire fraud when an asset's classification is uncertain. That theory has limits. The information must be "property." The Second Circuit vacated the first NFT insider trading conviction because the jury was not required to find that the information had commercial value to its owner. United States v. Chastain, No. 23-7038 (2d Cir. July 31, 2025). Government regulatory interests are not property under the fraud statutes. Kelly v. United States, 590 U.S. 391 (2020). Whether confidential government policy information qualifies as property of the United States remains unsettled.
Market Manipulation Theories
Committees will also examine how Trump-linked tokens traded after launch. They will ask who provided market-making services, on what terms, and whether volume was genuine. Wash trading, spoofing, and pump-and-dump schemes can be charged as securities manipulation under Title 15, as commodities manipulation or spoofing under 7 U.S.C. §§ 6c(a)(5) and 13(a)(2), or as wire fraud.
DOJ has shown how these cases are built. In Operation Token Mirrors, the FBI created its own token and charged 18 individuals and entities, including four market makers accused of wash trading for token issuers. The government also faces limits. In May 2025, a federal judge vacated the commodities fraud and manipulation convictions of Mango Markets trader Avraham Eisenberg for improper venue and acquitted him of wire fraud because the government had not proved a false representation to a permissionless protocol. Legitimate market making provides liquidity. The line is intent to create a false appearance of price or volume, and intent is proved or disproved through trading records, communications, and expert analysis.
Defending a Trading Inquiry
Trading cases turn on four questions. Was the information material and nonpublic, or already reflected in news reports, public statements, or on-chain activity? Did the trader know the information came from a breach of duty? Does the trading pattern differ from the account's prior activity? Is the wallet or account actually attributable to the person? Each question is answered with data. The defense reconstructs the public information environment on the trade date, the account's full trading history, and the chain of attribution from wallet to person.
Who Is in the Crosshairs
Subpoenas will reach well beyond the principals.
Many of these people have done nothing wrong. They will still face document demands, interviews, and public testimony, and each response becomes part of a permanent record.
How Congress Investigates: Authority and Tools
Congress's power to investigate is implied from its power to legislate. The Supreme Court recognized it in McGrain v. Daugherty, 273 U.S. 135 (1927), a case arising from the Teapot Dome scandal. The power reaches private individuals and companies as well as government officials. The Congressional Research Service's Congressional Oversight Manual, updated in March 2026, describes the available tools.
The Legal Limits
An investigation must serve a valid legislative purpose. Congress has no general power to expose private affairs for the sake of exposure. Watkins v. United States, 354 U.S. 178 (1957). A question must be pertinent to the subject under inquiry, and the witness is entitled to know what that subject is. For subpoenas seeking a sitting President's personal information, Mazars requires courts to weigh the legislative need, the breadth of the request, the evidence offered, and the burden on the presidency. Courts have not applied that heightened test to private witnesses.
The Speech or Debate Clause limits how witnesses can challenge a subpoena. A court will not enjoin a committee from issuing or enforcing one. Eastland v. U.S. Servicemen's Fund, 421 U.S. 491 (1975). Challenges come through negotiation, as defenses in a contempt proceeding, or in suits against third parties who hold the witness's records.
The Investigative Toolkit
Letter requests. A chair writes to request documents or information. Compliance is voluntary, and the letter usually signals that a subpoena will follow if cooperation stalls.
Document subpoenas. A subpoena duces tecum compels production of records, including emails, messaging apps, wallet addresses, and transaction data.
Third-party subpoenas. Committees subpoena banks, exchanges, prediction markets, custodians, and accountants directly. The Mazars and Deutsche Bank subpoenas followed this model. Federal financial privacy statutes that restrict agency access to bank records do not bind Congress.
Transcribed interviews. Staff question a witness on the record. The witness is often not sworn, but false statements are still crimes.
Depositions. House rules authorize staff depositions under oath. PSI and other Senate committees have deposition authority under their own rules.
Hearings. Members question sworn witnesses in public.
Agency records and financial intelligence. Committees demand documents from Treasury, the SEC, the CFTC, and the Justice Department, including suspicious activity report data.
Immunity orders. With a two-thirds vote of the full committee and ten days' notice to the Attorney General, a committee can obtain a court order compelling a witness who invokes the Fifth Amendment to testify. 18 U.S.C. § 6005.
Staff reports and referrals. Committees publish findings and send criminal referrals to the Justice Department, state prosecutors, and regulators.
Contempt. Criminal contempt referral, civil enforcement litigation, and the long-dormant inherent contempt power are available against witnesses who refuse to comply.
The Investigative Steps: From First Letter to Criminal Referral
Staff typically work from records and junior witnesses toward principals, much as prosecutors do before a grand jury.
Step 1: Organization. The 120th Congress convenes on January 3, 2027. Committees adopt rules, hire investigative counsel, and set budgets. House committees must adopt oversight plans early in the session. Reuters reported that probes could launch as early as February.
Step 2: Preservation letters. The first contact is often a demand to preserve records, including messages on Signal, Telegram, and WhatsApp. Destroying or concealing records after notice of a congressional inquiry can be charged as obstruction under 18 U.S.C. § 1505. Auto-delete settings on messaging apps must be addressed at this stage.
Step 3: Voluntary document requests. Committees negotiate custodians, date ranges, and search terms, and productions roll out in tranches. The scope agreed at this stage usually governs later requests.
Step 4: Subpoenas. If negotiation fails, the chair issues a subpoena for documents, testimony, or both.
Step 5: Third-party collection. Staff subpoena banks, exchanges, and custodians and trace wallets through public blockchain data.
Step 6: Transcribed interviews. Junior employees, assistants, and outside vendors are usually interviewed first. Their accounts are used to test senior witnesses.
Step 7: Depositions. Key witnesses testify under oath, usually behind closed doors. The committee can release transcripts later.
Step 8: Public hearings. Principals testify on camera. A witness who intends to invoke the Fifth Amendment may be required to do so in public.
Step 9: Staff reports. The committee publishes findings, often with exhibits drawn from subpoenaed documents.
Step 10: Referrals and enforcement. The committee sends criminal referrals to the Justice Department, state prosecutors, the SEC, the CFTC, or the IRS, and pursues contempt against witnesses who refused to comply.
What a Referral Does, and What It Does Not Do
A referral does not compel a prosecution, and the current Justice Department is unlikely to act on referrals targeting the President's family or allies. The general federal limitations period is five years. 18 U.S.C. § 3282. Testimony given in 2027 remains chargeable into 2032, after a new administration takes office in January 2029.
Congressional records also feed prosecutions directly. In April 2026, a former senior adviser to Dr. Anthony Fauci was indicted on records concealment and falsification charges after a House Oversight select subcommittee reviewed his emails and questioned him under oath. Contempt referrals can end in prison when prosecutors act on them. Stephen Bannon and Peter Navarro were each convicted of contempt of Congress and served four-month sentences.
State attorneys general can use a published congressional record to open their own investigations. A presidential pardon does not reach state crimes.
Defense Strategies for Witnesses and Companies
Congressional investigations are political proceedings that can produce criminal referrals. Defense strategy has to address both. The firm represents witnesses and companies before House and Senate committees through its congressional investigations defense practice.
Engage Early and Negotiate Scope
Most disputes with committees are resolved through negotiation, known as the accommodation process. Staff want documents and answers, and they generally prefer to avoid litigation. Early engagement lets counsel narrow custodians and date ranges, set rolling production schedules, request confidential treatment, and substitute a staff interview for a public hearing. Unanswered letters usually lead to subpoenas, and subpoena disputes play out in public. Work done before the new Congress convenes, including privileged internal reviews and preservation, shortens the response time once letters arrive.
Test Jurisdiction, Purpose, and Pertinency
A committee must act within its jurisdiction and for a valid legislative purpose, and its questions must be pertinent to the subject under inquiry. These objections must be raised in writing and on the record. An objection not made at the time is usually lost in a later contempt case. Requests that sweep in political donations or associations may also raise First Amendment objections. In the D.C. Circuit, reliance on the advice of counsel is not a defense to criminal contempt of Congress.
Know Which Privileges Congress Recognizes
Committees take the position that common-law privileges, including the attorney-client privilege and work product protection, do not bind Congress. They rule on privilege claims case by case and often accommodate well-supported claims. Counsel prepare privilege logs, negotiate early, and weigh a second risk: producing privileged material to Congress may waive the privilege in later litigation.
Protect Wallet Data
Wallet addresses carry a risk that bank records do not. Once a committee publishes an address in a report or exhibit, anyone can trace every past and future transaction tied to it. Journalists, on-chain analysts, civil plaintiffs, and criminals seeking targets all use that data. Counsel can request confidential treatment, redaction of addresses from public exhibits, or production in a form that answers the committee's question without disclosing the full wallet history.
Test the Tracing
Committee staff rely on blockchain analytics vendors and the same clustering methods federal agents use. Those methods rest on inferences. Clustering heuristics can group unrelated wallets, address labels can be wrong, and commingled funds can inflate proceeds figures. Attributing a wallet to a person is a conclusion that requires evidence. When a staff report attributes wallets or proceeds to a client, counsel can submit a written response for the record supported by independent forensic analysis.
Address Foreign Witnesses and Foreign Law
Committees generally cannot compel a foreign national outside the United States, but they can serve a subpoena when that person enters the country. International clients evaluate travel plans with that in mind. Foreign data-protection and bank-secrecy laws may conflict with a committee's demand. Committees are not bound by those laws, but the conflict is a legitimate basis to negotiate scope and format.
Use the Fifth Amendment Deliberately
The privilege against self-incrimination applies before Congress. Quinn v. United States, 349 U.S. 155 (1955). No particular words are required, so long as the committee is on notice. The privilege has limits.
Companies have no privilege. A corporate custodian must produce corporate records even if they incriminate the custodian. Braswell v. United States, 487 U.S. 99 (1988).
Individuals may resist producing personal records when the act of production itself would be testimonial and incriminating. United States v. Hubbell, 530 U.S. 27 (2000).
A pardon narrows the privilege. A witness pardoned for specific federal conduct faces no federal prosecution for it. The privilege still covers unpardoned conduct and exposure to state prosecution.
Invocation carries costs. A public invocation is widely reported as an admission, although the law does not treat it as one. In parallel civil cases, an adversary may seek an adverse inference.
Treat Immunity With Care
A compelled immunity order under § 6005 bars the government from using the testimony or anything derived from it. Kastigar v. United States, 406 U.S. 441 (1972). It does not bar prosecution based on independent evidence. Immunized congressional testimony can also derail a later case. The D.C. Circuit vacated Oliver North's convictions because trial witnesses had been exposed to his immunized, televised testimony. United States v. North, 910 F.2d 843 (D.C. Cir. 1990). Immunity removes the privilege, and false immunized testimony remains perjury.
Get Every Word Right
The False Statements Act reaches congressional investigations conducted under committee authority. 18 U.S.C. § 1001(c). It applies to unsworn transcribed interviews and written submissions. Perjury under 18 U.S.C. § 1621 applies to sworn testimony. Each carries up to five years in prison. The statutory recantation defense in 18 U.S.C. § 1623 applies to court and grand jury proceedings, not to Congress, so accuracy depends on preparation before the witness speaks.
Manage the Parallel Proceedings
Every document produced and every answer given will be available to the Justice Department, the SEC, the CFTC, state attorneys general, and civil plaintiffs. Counsel coordinate positions across those forums before the first production. Companies and individuals often need separate counsel, because their interests diverge once responsibility is assigned. Common-interest agreements can preserve some coordination but do not guarantee confidentiality. Public statements by a company or its spokespeople become part of the record and must match the testimony.
Check Insurance Coverage Early
Directors and officers policies define a covered "claim" in different ways. Some reach congressional subpoenas and document requests, and some do not. Notice provisions can run from the first letter. A prompt coverage review can determine whether the policy pays for counsel during the investigation.
Prepare Witnesses Like Trial Witnesses
Preparation for a committee deposition or hearing mirrors preparation for cross-examination. It includes review of every document the committee holds, mock questioning by counsel who have examined witnesses at trial, and a clear understanding of the investigation's scope. The goal is accurate, complete, and consistent testimony, because prosecutors and regulators may review the transcript years later.
Defense Counsel in Congressional and Crypto Investigations
The likely congressional probes rest on three theories: public corruption, insider trading and market manipulation, and money laundering. Armstrong & Bradylyons PLLC was founded by former federal prosecutors who led cases in each area.
Scott Armstrong served nearly a decade in the Justice Department's Criminal Division Fraud Section, including as an Assistant Chief in the Market Integrity and Major Frauds Unit. He supervised prosecutions involving cryptocurrency fraud, crypto Ponzi schemes, pig butchering, and digital asset investment fraud. He was lead trial counsel in the first cryptocurrency market manipulation case charged under Title 15, involving more than $300 million in spoof and wash trades. He served as co-lead trial counsel in the nation's leading market manipulation prosecution of two senior traders for manipulation of precious-metals futures, led the first cherry-picking case against a commodity trading advisor involving cryptocurrency futures, and tried a $650 million Ponzi scheme case to verdict.
Drew Bradylyons served as Chief of the Financial Crimes and Public Corruption Unit at the U.S. Attorney's Office for the Eastern District of Virginia. He supervised cryptocurrency Ponzi prosecutions involving hundreds of millions of dollars in losses and coordinated parallel criminal and civil enforcement with the SEC and CFTC. At the Fraud Section, he prosecuted a first-of-its-kind commodities insider trading ring in natural gas futures.
Together, the firm's attorneys have more than 25 years of combined DOJ experience and 25 federal jury trials. Through its cryptocurrency fraud and money laundering defense practice, the firm represents domestic and international clients in complex DOJ crypto-tracing investigations, including matters involving multi-million-dollar freeze and seizure orders. Those cases turn on blockchain tracing analyses, wallet attribution, exchange know-your-customer records, and proof of beneficial ownership, which is the evidence congressional investigators will demand. The firm tests how investigators cluster wallets, attribute them to individuals, and calculate proceeds.
The firm has also defended clients in multi-million-dollar DOJ investigations and prosecutions across crypto fraud and money laundering, including a nine-figure cryptocurrency theft case. It has represented clients in disputes over millions of dollars in allegedly ill-gotten crypto gains, obtaining reductions of up to 75% of the amounts demanded.
Congressional subpoenas often precede DOJ, SEC, CFTC, and state proceedings. Armstrong and Bradylyons built fraud, manipulation, corruption, and laundering cases from the government's side. Through the firm's white-collar defense and federal trial practice, they now defend executives, companies, and individual witnesses from Washington, D.C. and in federal districts nationwide.
Frequently Asked Questions
Could a Democratic Congress investigate the Trump family's cryptocurrency businesses?
Yes. Control of either the House or the Senate gives Democrats subpoena power and investigative budgets. On September 28, 2026, Reuters reported that Trump-linked crypto firms and 1789 Capital are areas of particular interest to Representative Jamie Raskin and Senator Richard Blumenthal, and that probes could begin as early as February 2027.
The investigations would likely run through House Oversight, House Judiciary, House Financial Services, the Senate Permanent Subcommittee on Investigations, and Senate Banking. Congressional investigative power reaches private companies and individuals as well as government officials. The Supreme Court's decision in Trump v. Mazars USA, LLP, 591 U.S. 848 (2020), applies a heightened test to subpoenas seeking a sitting President's personal information. Investors, business partners, exchanges, and executives connected to those ventures face the ordinary standard.
Can a congressional committee subpoena a private cryptocurrency company or executive?
Yes. Congress may compel documents and testimony from any person or company when the inquiry serves a valid legislative purpose and the questions are pertinent to the subject under investigation. Watkins v. United States, 354 U.S. 178 (1957). Committees also subpoena third parties directly, including banks, exchanges, prediction markets, custodians, and accounting firms. Federal financial privacy statutes that limit agency access to bank records do not restrict Congress.
Under the Speech or Debate Clause, a court will not enjoin a committee subpoena. Eastland v. U.S. Servicemen's Fund, 421 U.S. 491 (1975). The recipient's options are negotiation, written objections preserved for any later contempt proceeding, and, in some cases, litigation against a third-party custodian. Armstrong & Bradylyons defends individuals in federal crypto investigations and draws on its founders' years as DOJ prosecutors to assess how produced records will be used.
Is insider trading on cryptocurrency or prediction markets illegal?
It can be, depending on the asset and the source of the information. If a token is a security, trading on material nonpublic information in breach of a duty violates Section 10(b) under the misappropriation theory. For commodities, including spot bitcoin and event contracts, the CFTC relies on Section 6(c)(1) of the Commodity Exchange Act and Rule 180.1. Trading on nonpublic information obtained from a federal agency or employee is separately prohibited by 7 U.S.C. § 6c(a)(4).
In April 2026, prosecutors and the CFTC used that provision for the first time, charging an Army soldier with betting on Polymarket using classified information about the Maduro operation. In May 2026, they charged a Google engineer with trading Polymarket contracts on confidential company data. Wire fraud is also charged, but the Second Circuit held in United States v. Chastain (2025) that the information must have commercial value to its owner. Drew Bradylyons prosecuted a first-of-its-kind commodities insider trading ring in natural gas futures at DOJ's Fraud Section.
What conduct counts as crypto market manipulation?
Federal prosecutors and regulators charge wash trading, spoofing, pump-and-dump schemes, and coordinated trading intended to create a false appearance of price or volume. Depending on the asset, these cases proceed as securities manipulation under Title 15, as commodities manipulation or spoofing under the Commodity Exchange Act, or as wire fraud. In Operation Token Mirrors, the FBI created its own token and charged 18 individuals and entities, including market makers accused of wash trading for token issuers.
The line between legitimate trading and manipulation is intent. Market makers provide liquidity lawfully. Large trades that move prices are not manipulation by themselves. In 2025, a federal judge vacated the manipulation and commodities fraud convictions of Mango Markets trader Avraham Eisenberg and acquitted him of wire fraud. Scott Armstrong was lead trial counsel in the first cryptocurrency market manipulation case charged under Title 15, involving more than $300 million in spoof and wash trades.
Can a witness invoke the Fifth Amendment before Congress?
Yes. The privilege against self-incrimination applies in congressional proceedings. Quinn v. United States, 349 U.S. 155 (1955). A witness need not use particular words, so long as the committee understands that the privilege is being claimed. The privilege belongs to individuals. A company cannot invoke it, and a corporate records custodian must produce company records.
A committee can override the privilege by obtaining a court order under 18 U.S.C. § 6005, which requires a two-thirds vote of the full committee and ten days' notice to the Attorney General. The order grants use and derivative use immunity but does not bar prosecution based on independent evidence. Whether to invoke is a strategic decision that depends on the witness's exposure in every other forum, including state prosecution and civil litigation.
Is lying to Congress a federal crime, and how long can prosecutors bring charges?
Yes. The False Statements Act, 18 U.S.C. § 1001(c), covers investigations conducted under the authority of a congressional committee. It applies to unsworn statements in transcribed interviews, letters, and written responses. Perjury under 18 U.S.C. § 1621 covers sworn testimony. Each offense carries up to five years in prison.
The general limitations period for these crimes is five years under 18 U.S.C. § 3282. A false statement made to a committee in 2027 can be charged into 2032, after the current administration leaves office. Congressional testimony has no statutory recantation safe harbor, because the recantation defense in 18 U.S.C. § 1623 applies only to court and grand jury proceedings. Scott Armstrong and Drew Bradylyons, former DOJ prosecutors with 25 federal jury trials between them, prepare witnesses knowing how prosecutors read a transcript.
What happens when someone refuses to comply with a congressional subpoena?
Congress has three enforcement options. First, either chamber may certify a witness for criminal contempt under 2 U.S.C. §§ 192 and 194. The U.S. Attorney then decides whether to present the case to a grand jury. Contempt is a misdemeanor punishable by one to twelve months in jail. Stephen Bannon and Peter Navarro were convicted and each served four months.
Second, a committee may sue to enforce the subpoena. The Senate has a dedicated civil enforcement statute, 28 U.S.C. § 1365, that applies to private individuals and companies. A witness who defies the resulting court order faces contempt of court. Third, Congress retains an inherent contempt power it has not used in nearly a century. In the D.C. Circuit, advice of counsel is not a defense to criminal contempt of Congress.
What is the difference between a transcribed interview and a deposition?
A transcribed interview is a voluntary session in which committee staff question a witness on the record. The witness is usually not under oath. A deposition is compelled, typically by subpoena, and taken under oath. House rules authorize staff to conduct depositions, and Senate committees such as the Permanent Subcommittee on Investigations have deposition authority under their own rules.
Both formats produce transcripts the committee can release, and both carry criminal exposure. False statements in an unsworn interview can be charged under 18 U.S.C. § 1001, and false sworn testimony can be charged as perjury. Witnesses may bring personal counsel to both. Committees often begin with interviews of junior employees and use that testimony to question senior witnesses later.
Can a congressional investigation lead to crypto fraud or money laundering charges?
Yes. Congress cannot bring charges, but committees send criminal referrals to the Justice Department, state prosecutors, the SEC, the CFTC, and the IRS. Published staff reports, exhibits, and transcripts also give prosecutors a roadmap. In April 2026, a former senior NIH adviser was indicted on records concealment and falsification charges after a House select subcommittee examined his emails and took his sworn testimony.
Referrals targeting allies of a sitting administration may not be acted on immediately. The five-year limitations period allows a later administration to act on the same record, and a presidential pardon does not reach state crimes. The firm's attorneys prosecuted cryptocurrency Ponzi schemes, market manipulation, and money laundering at DOJ and now defend individuals facing the same theories.
Does the attorney-client privilege protect documents from a congressional subpoena?
Not automatically. Congressional committees take the position that common-law privileges, including the attorney-client privilege and attorney work product protection, do not bind Congress. Committees decide privilege claims case by case. Many accommodate well-documented claims, especially when counsel raise them early and provide a privilege log.
Two risks remain. A committee can overrule the claim and demand production. Producing privileged material to Congress can also waive the privilege in later litigation with regulators or private parties. Companies facing a congressional inquiry usually conduct any internal investigation under privilege and decide what to produce after assessing exposure across every forum.
Do corporate employees need separate counsel in a congressional investigation?
Often. Company counsel's client is the company. Company lawyers who interview employees give Upjohn warnings, which explain that the privilege belongs to the company and the company may waive it. Once a committee begins assigning responsibility, the interests of a company and its employees can diverge.
An employee may have Fifth Amendment exposure the company does not share. A company may decide that cooperation requires identifying individual decision-makers. Separate counsel lets each witness receive advice based on personal exposure. Common-interest agreements can preserve some coordination among counsel but do not guarantee confidentiality.
