The Office of Inspector General at the Treasury Department is launching an audit of the security controls for the federal government’s payment system after Senate Democrats sounded the alarm regarding the access provided to Elon Musk’s Department of Government Efficiency team.

In a letter to Senate Democrats, Treasury Deputy Inspector General Loren Sciurba said that the office opened an audit into the Bureau of Fiscal Service’s payments systems on Feb

The audit will also review the past two years of the system’s transactions as it relates to Musk’s assertion of “alleged fraudulent payments.”
