A bipartisan group of U.S. senators is urging the Treasury Department to ensure state regulators are included in the implementation of the GENIUS Act, which governs stablecoin issuers. The senators, led by Republican Cynthia Lummis, have expressed concerns that state regulators are being sidelined in the process. They emphasize the importance of establishing clear principles for assessing state regulatory frameworks to ensure they align with federal standards. The lawmakers' letter highlights the need for Treasury to address procedural requirements for state certification, which were omitted in the proposed principles.
