EFF and a coalition of privacy defenders have filed a lawsuit today asking a federal court to block Elon Musk’s Department of Government Efficiency (DOGE) from accessing the private information of millions of Americans that is stored by the Office of Personnel Management (OPM), and to delete any data that has been collected or removed from databases thus far.

This brazen ransacking of Americans’ sensitive data is unheard of in scale. With our co-counsel Lex Lumina, State Democracy Defenders Fund, and the Chandra Law Firm, we represent current and former federal employees whose privacy has been violated. We are asking the court for a temporary restraining order to immediately cease this dangerous and illegal intrusion. This massive trove of information includes private demographic data and work histories of essentially all current and former federal employees and contractors as well as federal job applicants. Access is restricted by the federal Privacy Act of 1974. Last week, a federal judge temporarily blocked DOGE from accessing a critical Treasury payment system under a similar lawsuit.
