A major U.S. security contractor is under scrutiny for its security screening process after it continued to employ Orlando shooter Omar Mateen despite two FBI inquiries into his ties to terrorism.
Mateen, who pledged allegiance to ISIS before shooting up a popular gay nightclub in Orlando on Sunday, worked for the security firm G4S since 2007. Forty-nine people and Mateen were killed in the attack.
G4S is a British security firm that has contracted with the Department of Homeland Security and the Department of Defense.
A spokesperson for G4S told the Washington Free Beacon on Monday that Mateen did not have a U.S. security clearance and did not work on any federal contracts or have access to sensitive federal information.
Mateen worked as an armed custom protection officer at a Florida courthouse until three years ago. He went on to work as a security guard at a residential community.
