OPM's top technology official retires amid data breach fallout

Donna Seymour is the second high-ranking official to leave OPM since the hacking of personal information of 22 million people was disclosed last July

The top technology official at the US Office of Personnel Management announced her retirement on Monday amid calls for her ouster by some Republican lawmakers.

Donna Seymour, chief information officer, said in an email to her colleagues that was seen by Reuters that leaving was a "very tough decision". She added that she felt it was in the "agency's best interest that my presence does not distract from the great work this team does every single day".
