Staffers from billionaire Elon Musk’s “Department of Government Efficiency” had unauthorized access to sensitive information inside the Social Security Administration and may even have used it in coordination with an outside advocacy group, the Trump administration said in court.

The Justice Department said in a Friday “notice of corrections for the record” that the administration had uncovered “communications, use of data, and other actions by the then-SSA DOGE Team that were potentially outside of SSA policy” or in violation of a court order stemming from unions’ efforts to block DOGE from accessing people’s data.

The filing reveals officials falsely stated in the court case that DOGE team members had no access to personal identifying information when they actually did in several specific instances. In one case, DOGE staffers shared with their affiliates in other agencies an email attachment containing approximately a thousand people’s names and addresses.

In another instance, an advocacy group asked two members of the DOGE squad for help analyzing voter rolls the group had acquired with an eye toward overturning election results in certain states. The filing says there’s no evidence the staffers shared data with the group.
