Same company background-checked both Navy Yard shooter & Snowden

The company that scrutinized former intelligence agency contractor Edward Snowden for US government security clearance has said it had also checked the background of the Navy Yard shooter. USIS, working as a contractor for the Office of Personnel Management (OPM), conducted a background review of Aaron Alexis, Reuters reported. He was identified by law enforcement authorities as the shooter who killed 12 people at the Washington Navy Yard before he was shot dead on September 16. Earlier this year, USIS became the focus of congressional scrutiny because the company handled the most recent background investigation of Snowden.
