Attorney General William P. Barr Announces the Findings of the Criminal Investigation into the December 2019 Shooting at Pensacola Naval Air Station

The evidence shows that the shooter was motivated by jihadist ideology. During the course of the investigation, we learned that the shooter posted a message on social media on Sept. 11 of last year that said: “the countdown has begun.” Over Thanksgiving weekend, he visited the 9/11 Memorial in New York City. He also posted other anti-American, anti-Israeli, and jihadi messages on social media, and did so two hours before his attack at the naval base.

This was an act of terrorism.
