The chairman of a House subcommittee overseeing federal government operations is calling on Office of Personnel Management Director Katherine Archuleta to resign for failing to protect the personal data of millions of federal workers.

Rep. Mark Meadows, R-N.C., who chairs the House Oversight and Government Reform subcommittee on government operations, said Archuleta “failed to implement cybersecurity recommendations” issued by the agency’s inspector general, which led to the theft of data from up to 4 million current and former federal workers.
