Congressional Democrats are pressing the U.S. Labor Department to withdraw a March proposal they say could open $14.2 trillion in 401(k) assets to Bitcoin, crypto, and other alternative investments while weakening retirement saver protections. Bernie Sanders, Elizabeth Warren, and Bobby Scott argued the rule would weaken ERISA prudence standards and raise conflict-of-interest concerns tied to Trump family crypto ventures. Lawmakers also warned that expanding 401(k) access to volatile digital assets and alternatives could increase risks for retirement savers.
