Charles Borges, the agency's chief data officer, alleged that more than 300 million Americans’ Social Security data was put at risk by DOGE officials who uploaded sensitive information to a cloud account not subject to oversight. His disclosure was submitted to the special counsel’s office on Tuesday.

“After reporting internally to management and externally to regulators, serious data and security and integrity concerns impacting our citizens’ most sensitive personal data, I have suffered exclusion, isolation, internal strife, and a culture of fear, creating a hostile work environment and making work conditions intolerable,” Borges added.

The Government Accountability Project, which is representing him in his whistleblower case, posted Borges' resignation letter on its website Friday evening. Borges declined to comment.

“He no longer felt that he could continue to work for the Social Security Administration in good conscience, given what he had witnessed,” his attorney Andrea Meza said in a statement. She added that Borges would continue to work with the proper oversight bodies on the matter.
