A federal judge in New York early Saturday temporarily restricted the ability of Elon Musk’s Department of Government Efficiency to access the Treasury Department payment system, saying that doing so was necessary to prevent the potential disclosure of sensitive and confidential information.

DOGE’s earlier actions at the Treasury have become a focus of congressional scrutiny and a federal court battle in recent days. Musk’s team initially tried to halt money going to the U.S. Agency for International Development from the Treasury’s payment system.
