US Senators Challenge DOJ's Prosecution of Crypto Mixers

Two US senators have questioned the Justice Department's legal basis for pursuing cryptocurrency mixing services as unlicensed money transmitters. They argue that this interpretation of the law contradicts previous Treasury Department guidance and could have serious implications for software developers.
In a letter dated May 9, Senators Ron Wyden (D-Ore.) and Cynthia Lummis (R-Wyo.) addressed Attorney General Merrick Garland, expressing concerns about the DOJ's actions against services like Samourai Wallet and Tornado Cash. The senators cited previous FinCEN guidance that non-custodial crypto services should not be considered money transmitters.
They argued that classifying software developers as criminals for creating code used by others sets a dangerous precedent. The letter also challenged the DOJ's argument that FinCEN guidance did not address the concept of "control," emphasizing that the law requires a service to control funds to be classified as a money transmitter.
