The Treasury Department is appointing an ally of billionaire Elon Musk’s U.S. DOGE Service to a senior position in the department overseeing the nation’s powerful payment systems, according to two people with knowledge of the matter,

US Treasury Secretary Scott Bessent said he personally vetted a senior Treasury employee on Elon Musk’s government efficiency team who has read-only access to federal payment data, and that there’s been no “tinkering” with the department’s payment systems.

Sources tell WIRED that the ability of DOGE’s Marko Elez to alter code controlling trillions in federal spending was rescinded days after US Treasury and White House officials said it didn’t exist.
