The Department of Government Efficiency, led by tech billionaire Elon Musk, has reportedly gained access to the Treasury Department's payment system.

Treasury Secretary Scott Bessent gave Mr. Musk’s representatives at the so-called Department of Government Efficiency a powerful tool to monitor and potentially limit government spending.

A senior U.S. lawmaker says representatives of Elon Musk were granted “full access” to a U.S. Treasury payments system used to disperse trillions of dollars to Americans each year, and warned that Musk’s access to the system poses a “national security risk.”
