Same Firm Vetted Snowden, D.C. Shooter

A government contractor that provided a background check for NSA leaker Edward Snowden also provided one for alleged Navy Yard shooter Aaron Alexis, the company said. USIS had previously denied any involvement with Alexis, but a spokesman said new information has revealed it had indeed vetted the former Navy reservist for his secret-level clearance in 2007. USIS, which handles about half of the clearance checks for the Office of Personnel Management, is currently the subject of a criminal investigation over allegations it misled the government about its thoroughness.
