Senator Cynthia Lummis (R-WY) has criticized the U.S. Department of Justice (DOJ) over its position on self-custody wallets, as stated in a recent post on her official X account. Lummis’ criticism follows the DOJ’s move to file unlicensed money-transmitting charges against crypto mixers Tornado Cash and Samourai Wallet, hinting at a possible protracted legal dispute.
