Democratic lawmakers are urging the Trump administration to scrap a proposal making it easier for 401(k)s and other retirement plans to offer investments in cryptocurrency, private equity and so-called alternative assets. In a letter to the Labor Department, Senators Elizabeth Warren and Bernie Sanders and Congressmember Bobby Scott warn, “This would strip long-held investor protections from retirement savers and encourage the use of more risky, complex, and expensive investments. The proposed rule is harmful to American workers.”
