Four U.S. law enforcement organizations — the National Sheriffs' Association, the National Association of Assistant United States Attorneys (NAAUSA), the National District Attorneys Association, and the International Association of Chiefs of Police (IACP) — have sent a formal joint letter to Acting Attorney General Todd Blanche and White House digital assets advisor Patrick Witt, raising serious concerns about specific provisions in the CLARITY Act (HR 3633). Together, these groups represent over 70,000 law enforcement professionals, and their collective opposition has become one of the biggest roadblocks to the bill reaching a Senate floor vote.
What Section 604 Contains and Why Law Enforcement Objects
The letter targets Section 604, also known as the Blockchain Regulatory Certainty Act (BRCA). Designed to protect non-custodial blockchain developers and service providers from being classified as money transmitters, the BRCA sounds pro-innovation on its surface. But law enforcement argues it goes too far. The core concern: the provision could create regulatory loopholes that exempt certain crypto participants — including mixers, tumblers, and some DeFi entities — from Know Your Customer (KYC) and Anti-Money Laundering (AML) reporting requirements. Traditional banks must follow these compliance rules; if crypto platforms can bypass them, investigators say it directly weakens their ability to trace illicit transactions and prosecute crypto crime.
The letter flags three specific risks: creating oversight gaps that hinder investigations into blockchain-based illicit finance, reducing accountability for certain crypto market participants compared to traditional financial institutions, and shielding high-risk tools like mixers and tumblers by classifying their operators outside money transmitter rules. Notably, two organizations that actively participated in negotiations — GLFOP and NAPOpolice — did not sign the letter, indicating the disagreement is not fully unified and talks are ongoing.
Senate Path Stalled: Timeline and Key Milestones
The Section 604 controversy has become a central sticking point delaying the CLARITY Act from advancing to a full Senate floor vote. The bill passed the House in July 2025 with strong bipartisan support — 294 to 134 — and includes provisions to establish clear SEC-CFTC jurisdiction over digital assets and a “mature blockchain” test for non-security classification. A House Financial Services Committee field hearing titled “Building the Future of Finance: How the CLARITY Act Unlocks Innovation” is scheduled for July 17, 2026 in New York City.
With roughly 40 legislative working days left in this Congress, the clock is tight. According to Forbes and senior industry analysts, the CLARITY Act, the crypto tax-related PARITY Act, and the BRCA may need to be bundled into a year-end budget package to pass at all. Compounding the situation, the CFTC is running four commissioners short, stalling regulatory decisions, and two longtime pro-crypto voices — SEC Commissioner Hester Peirce (departing November 2026) and Senator Cynthia Lummis (not seeking reelection) — are both stepping away, removing key advocates.
What to watch next: The July 17 hearing in New York could set the tone for the rest of 2026's crypto legislative season. Any compromise on Section 604 that satisfies law enforcement without gutting developer protections will be the key breakthrough. If standalone passage stalls, year-end budget bundling becomes increasingly likely.
