Elon Musk said his “DOGE team” of government efficiency enforcers is shutting down payments to federal contractors, suggesting that the world’s richest man may have access to sensitive systems used at the US Treasury Department.

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.”
