Tornado Cash, a cryptocurrency mixer, was at the center of a heated debate during a congressional hearing as lawmakers discussed the effectiveness of a proposed bill in combating money laundering. Senator Warren criticized the bill, arguing it fails to adequately address the use of mixers like Tornado Cash by criminals and terrorists. She emphasized the need for stronger measures, stating, "What purpose does Tornado serve? Put your money in if you’re a terrorist!" Republican lawmakers defended the Clarity Act, asserting it provides sufficient tools to tackle such issues. Despite Warren's push for an amendment to strengthen the bill, supported by other Democrats, the amendment ultimately failed to pass.
