Orlando gunman Omar Mateen told a 911 dispatcher he was attacking an LGBT nightclub on behalf of the leader of the Islamic State, but he also expressed solidarity with the 2013 Boston Marathon bombers and an American suicide bomber in Syria who was not affiliated with Islamic State, FBI's Director James Comey said Monday.
Comey said Mateen's statements added "confusion" about his inspiration for the attack, because Mateen had expressed loyalty to Islamist groups and figures that are opposed to each other.
While working as a courthouse guard in 2013, Mateen made "inflammatory and contradictory" statements to co-workers about having relatives in Al Qaeda, the radical Sunni terrorist group, Comey said. Mateen also claimed to be a member of Hezbollah, Lebanon's Shiite militia, and his remarks drew an 11-month FBI investigation, Comey said. Both groups oppose Islamic State.
