Omar Mateen: Orlando shooter posted messages on Facebook pledging allegiance to the leader of ISIS and vowing more attacks

ORLANDO — On the day of his rampage at a gay nightclub, the Orlando shooter posted messages on Facebook pledging allegiance to the leader of the Islamic State and vowing that there would be more attacks in the coming days by the group in the United States, according to a letter sent to Facebook on Wednesday by Sen. Ron Johnson (R-Wis.), chairman of the Senate Homeland Security Committee.

“America and Russia stop bombing the Islamic state..I pledge my alliance to [Islamic State leader] abu bakr al Baghdadi ..may Allah accept me,” Omar Mateen wrote, according to the letter, which requested Facebook’s assistance in the investigation into the shooting that resulted in 49 deaths.

Mateen then posted, according to the letter: “The real muslims will never accept the filthy ways of the west” and “You kill innocent women and children by doing us airstrikes..now taste the Islamic state vengeance.”

At some point on Sunday, Mateen also searched on Facebook for “Pulse Orlando” and “Shooting,” according to Johnson.
