Office of Personnel Management Director Katherine Archuleta resigned from her position Friday, one day after the agency disclosed what it found in its investigation into the breaches on its computer systems, multiple media outlets are reporting.
National Journal reports Beth Cobert, deputy director for management at the Office of Management and Budget, will step into the acting director role at OPM.
Archuleta became director of OPM in November 2013 after what was then the first recorded vote on the position in the agency’s history.
Thursday, OPM said 22.1 million federal employees and contractors had their personal information compromised across two breaches that targeted files on security clearances and background checks, as well as a database of personnel records.
According to CNN, U.S. investigators believe hackers either within or backed by China’s government carried out the breach on OPM’s systems.
OPM — the federal government’s main human resources agency — has told lawmakers it has had five large breaches on its computer networks since mid-2012, CNN reports.
