Four Tennessee Marines are dead after being attacked at a military recruiting office in Chattanooga, Tennessee. We have been informed by law enforcement and the United States Justice Department that the shooter has been identified as Muhammad Youssef Abdulazeez. Investigators are treating the situation as a domestic terrorist attack. I am absolutely shocked and heartbroken. Why did the NSA not prevent this from happening? Hundreds of FBI agents are entering the state and the State Capitol is on high security alert. Additionally, other federal military installations are on high alert. Moments after Abdulazeez attacked two separate Tennessee military installations, ISIS sent out a tweet referencing Chattanooga. It has also been reported that Abdulazeez is a Kuwaiti national. I will keep you all updated as I learn more.
