DOJ Warns CLARITY Act Could Weaken Crypto Crime Cases

Section 604 at the Centre of the Debate

The U.S. Department of Justice's Criminal Division has raised concerns that a key provision of the Digital Asset Market Clarity Act could limit its ability to pursue money laundering and other financial crimes involving digital assets. The bill, known as the CLARITY Act, advanced out of the Senate Banking Committee in May 2026 with a 15-9 vote and is designed to bring a unified regulatory framework to crypto markets.

The specific flashpoint is Section 604 of the CLARITY Act, which provides broad exemptions for decentralized services, mixers, tumblers, and automated protocols. Law enforcement groups warn that Section 604 could create gaps in oversight and make it harder to investigate and prosecute illicit crypto activity, arguing that its language contains broad exemptions that could shield individuals or entities that facilitate the movement of crypto assets from regulatory accountability.

Four major U.S. law enforcement organizations sent a joint letter to Acting Attorney General Todd Blanche and White House crypto adviser Patrick Witt on June 23, warning that Section 604 could create oversight gaps and weaken investigative tools used in crypto crime cases. The coalition represents more than 70,000 U.S. prosecutors, police chiefs, sheriffs and other law enforcement professionals. The coalition said criminal organisations increasingly rely on digital assets to facilitate offences including narcotics trafficking, fraud, child exploitation, ransomware attacks, sanctions evasion, terrorism financing and organised retail crime.

Industry and White House Push Back

The DOJ further said the bill would not restrict its ability to investigate or prosecute criminal conduct involving digital assets, including drug trafficking, human smuggling, and terrorism financing. White House crypto adviser Patrick Witt has previously described the bill as a "pro-regulatory, pro-enforcement" measure. The Blockchain Association has pushed back against the law enforcement critique, arguing that the act actually expands law enforcement's toolkit against fraud and laundering, and that bringing more crypto businesses under the Bank Secrecy Act umbrella is a net positive for enforcement, even if certain categories of decentralized protocols receive different treatment.

The White House is expected to meet with representatives of law enforcement as administration officials continue their efforts to help advance the Senate's crypto market structure bill. The bill's path remains uncertain. Prediction market odds for the CLARITY Act's passage have dropped from above 75% to around 42% as the controversy intensifies. Senators Cynthia Lummis and Tim Scott have been pushing for a Senate floor vote before the August 2026 recess. The measure still has a long way to go before becoming law, given both powerful opposition and the fact that it would need to clear the full Senate as well as the House before heading to President Donald Trump's desk.
