Chief Data Officer Charles Borges said sensitive data was uploaded to a digital cloud, risking the security of critical personal information for more than 300 million people.

A whistleblower says more than 300 million Americans' Social Security data was put at risk after Department of Government Efficiency officials uploaded sensitive information to a cloud account not subject to oversight.

The private information of hundreds of millions of Americans is at risk after the Department of Government Efficiency uploaded a copy of a vast Social Security database to a cloud server in June, according to a whistleblower complaint from the chief data officer for the Social Security Administration.
