The embattled technology head at the Office of Personnel Management announced her retirement on Monday, just two days before she was set to testify on the agency’s failings before a House committee.

“Leaving OPM at this time was a very tough decision for me, but I feel it is in the agency’s best interest that my presence does not distract from the great work this team does every single day for this agency and the American people,” Chief Information Officer Donna Seymour said in a Monday afternoon message to the agency’s employees.
