A new Senate report claims DOGE put every American’s Social Security number at risk—and that officials at federal agencies essentially obstructed an investigation, all but denying DOGE even exists.

From its inception, Elon Musk’s so-called Department of Government Efficiency (DOGE) operated as a rogue entity within the US government, slashing staff and funding, gaining access to government systems, and overriding agency decisionmaking—all without oversight from officials who have little understanding of its reach and methods.

A new report issued by the Senate Committee on Homeland Security and Governmental Affairs (HSGAC) on Thursday adds new insight on how this incursion happened, while raising grave concerns about the possibility of a catastrophic data breach that would affect all Americans and serious questions about who DOGE operatives answer to.

Oversight staff detail how DOGE gained control over federal agencies, focusing their probe on three of DOGE’s primary targets: the General Services Administration (GSA), the Office of Personnel Management (OPM), and the Social Security Administration (SSA).
