The Treasury Department's Office of Inspector General on Friday said it was launching an audit of the security controls for the federal government's payment system, after Democratic senators raised red flags about the access provided to Trump aide Elon Musk's Department of Government Efficiency team.

Two government watchdogs will investigate the Department of Government Efficiency’s access to sensitive Treasury payments systems, they confirmed in letters to Congress.

The department’s deputy inspector general said the audit will examine access and security controls on Bureau of Fiscal Service systems.
