US Treasury Department and White House officials have repeatedly denied that technologists associated with Elon Musks so-called Department of Government Efficiency (DOGE) had the ability to rewrite the code of the payment system through which the vast majority of federal spending flows. WIRED reporting shows, however, that at the time these statements were made, a DOGE operative did in fact have write access. Not only that, but sources tell WIRED that at least one note was added to Treasury records indicating that he no longer had write access before senior IT staff stated it was actually rescinded.Marko Elez, a 25-year-old DOGE technologist, was recently installed at the Treasury Department as a special government employee. One of a number of young men identified by WIRED who have little to no government experience but are currently associated with DOGE, Elez previously worked for SpaceX, Musks space company, and X, Musks social media company. Elez resigned Thursday after The Wall Street Journal inquired about his connections to a deleted social-media account that advocated for racism and eugenics.As WIRED has reported, Elez was granted privileges including the ability to not just read but write code on two of the most sensitive systems in the US government: the Payment Automation Manager (PAM) and Secure Payment System (SPS) at the Bureau of the Fiscal Service (BFS), an agency that according to Treasury records paid out $5.45 trillion in fiscal year 2024. Reporting from Talking Points Memo confirmed that Treasury employees were concerned that Elez had already made extensive changes to code within the Treasury system. The payments processed by BFS include federal tax returns, Social Security benefits, Supplemental Security Income benefits, and veterans pay.Over the last week, the nuts and bolts of DOGEs access to the Treasury has been at the center of an escalating crisis.On January 31, David Lebryk, the most senior career civil servant in the Treasury, announced he would retire; he had been placed on administrative leave after refusing to give Musks DOGE team access to the federal payment system. The next morning, sources tell WIRED, Elez was granted read and write access to PAM and SPS.On February 3, Politico reported that Treasury Secretary Scott Bessent told Republican lawmakers in the House Financial Services Committee that Musk and DOGE didnt have control over key Treasury systems. The same day, The New York Times reported that Karoline Leavitt, the White House press secretary, said that DOGEs access was read-only.Got a Tip?Are you a current or former employee at the Treasury or Bureau of the Fiscal Service? Or other government tech worker? We'd like to hear from you.

(CNN reported on Thursday that Musk associates had demanded that Treasury pause authorized payments to USAID, precipitating Lebryks resignation.)On February 4, WIRED reported that Elez did, in fact, have admin access to PAM and SPS. Talking Points Memo reported later that day that Elez had made extensive changes to the code base for these critical payment systems. In a letter that same day that did not mention Musk or DOGE, Treasury official Jonathan Blum wrote to Senator Ron Wyden of Oregon, Currently, Treasury staff members working with Tom Krause, a Treasury employee, will have read-only to the coded data of the Fiscal Services payment systems. (Krause is the top DOGE operative at Treasury and CEO of Cloud Software Group.) The letter did not say what kind of access the staff members actually had.
