WASHINGTON – 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.

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,” according to a letter from Loren J. Sciurba, Treasury’s deputy inspector general, that was obtained by The Associated Press.

The audit marks part of the broader effort led by Democratic lawmakers and federal employee unions to provide transparency and accountability about DOGE’s activities under President Donald Trump’s Republican administration. The Musk team has pushed for access to the government’s computer systems and sought to remove tens of thousands of federal workers.

“We expect to begin our fieldwork immediately,” Sciburba wrote. “Given the breadth of this effort, the audit will likely not be completed until August; however, we recognize the danger that improper access or inadequate controls can pose to the integrity of sensitive payment systems. As such, if critical issues come to light before that time, we will issue interim updates and reports.”

Tech billionaire Musk, who continues to control Tesla, X and SpaceX among other companies, claims to be finding waste, fraud and abuse while providing savings to taxpayers, many of his claims so far unsubstantiated. But there is a risk that his team’s aggressive efforts could lead to the failure of government computer systems and enable Musk and his partners to profit off private information maintained by the government.

Democratic Sens. Elizabeth Warren of Massachusetts and Ron Wyden of Oregon led the push for the inspector general office’s inquiry.

On Wednesday, Warren, Wyden and Sen. Jack Reed, D-Rhode Island, sent a letter to Treasury Secretary Scott Bessent noting the inconsistencies in the accounts provided by his department about DOGE.

“Your lack of candor about these events is deeply troubling given the threats to the economy and the public from DOGE’s meddling, and you need to provide a clear, complete, and public accounting of who accessed the systems, what they were doing, and why they were doing it,” the Democratic lawmakers wrote in their letter.

The Treasury Department provided conflicting information about DOGE’s access to the payment system. Initially, it claimed the access was read only, only to then acknowledge that a DOGE team member briefly had the ability to edit code, and then to say in an employee sworn statement that the ability to edit was granted by accident.

The 25-year-old employee granted the access, Marko Elez, resigned this month after racist posts were discovered on one of his social media accounts, only for Musk to call for his rehiring with the backing of Trump and Vice President JD Vance.

Advocacy groups and labor unions have filed lawsuits over DOGE’s potential unauthorized access to sensitive Treasury payment systems, and five former treasury secretaries have sounded the alarm on the risks associated with Musk’s DOGE accessing sensitive Treasury Department payment systems and potentially stopping congressionally authorized payments.

Earlier this week, the Treasury declined to brief a pair of the highest-ranking lawmakers on the Senate Finance Committee, including Wyden, on the ongoing controversy related to DOGE’s use of Treasury payment systems, citing ongoing litigation.
