The letter requests Facebook provide all data on the gunman's "activities on his account and any affiliated Facebook accounts, including but not limited to activity logs, Facebook timeline information, Facebook messages, photos, and posts."

According to the letter, on June 12 the day of the attack, Omar Mateen searched for "Pulse Orlando" and Shooting." After that he left chilling posts including "America and Russia stop bombing the Islamic state..I pledge my alliance to abu bakr al Baghdadi..may Allah accept me"... And his final post was "In the next few days you will see attacks from the Islamic state in the usa." These activities took place before and during the attack.

The letter also revealed that in May 2016, Mateen used Facebook to search for information on the San Beardino terrorists and on June 4, 2016, he searched "Baghdadi Speech."

Apart from the gunman's Facebook data, the letter also requests a briefing on the information available to Facebook prior to and during the attack. Facebook has until 5:00 June 29th to comply with the Senator's request.

Facebook didn't immediately respond to a request for comment.
