Company Behind Snowden Check Also Vetted D.C. Shooter

The same federal contractor that vetted Edward Snowden, who leaked information about classified U.S. spying programs, also performed a background check that let the Washington Navy Yard shooter obtain a security clearance.

Now the contractor, USIS, is drawing fire from a U.S. senator asking how Snowden and Navy Yard shooter Aaron Alexis slipped through the cracks. The vetting process has also been included in an inquiry by law enforcement agencies into Alexis’s activities before his deadly rampage this week.
