The U.S. government contractor that vetted Edward Snowden, who leaked information about national surveillance programs, said it also performed a background check on the Washington Navy Yard shooter.
USIS, a unit of Falls Church, Virginia-based Altegrity Inc., owned by Providence Equity Partners LLC, did Aaron Alexis’s background investigation in 2007, Ray Howell, a USIS spokesman, said in an e-mail. “Today we were informed that in 2007, USIS conducted a background check of Aaron Alexis” for the U.S. Office of Personnel Management, Howell said.
