Lawmakers push Treasury on crypto mixer risks

U.S. lawmakers, led by Rep. Sean Casten, urged the Treasury to address risks from crypto mixers like Tornado Cash, citing national security concerns. According to The Block, they requested data on activity since Tornado Cash's 2022 sanctions and asked if further actions, including secondary sanctions, are planned. Lawmakers also proposed a bill to block financial institutions from handling mixed funds during a study on illicit uses.
