Shooting suspect Mohammed Saeed Alshamrani, who was participating in a flight training program for foreign military personnel, reportedly had condemned the United States as a “nation of evil” in a manifesto posted to Twitter.
The official was briefed by federal investigators and spoke on condition of anonymity. He says authorities tell him one Saudi student was recording outside the building while the shooting took place.
Three people died and eight suffered injuries during Friday's shooting before a law enforcement officer shot the assailant dead.
AP reported that Alshamrani earlier in the week hosted a dinner party to watch videos of mass shootings.
