 The shooter is Thomas Matthew Crooks of Bethel Park, Pennsylvania. That's just about 45 minute drive from where we are right now. The shooter was up on that roof, we're told, for a very short time before he fired that weapon. The 20 year old was a registered Republican, according to state voting records. Police tell us Crooks was able to get up on that rooftop just about 200 yards or like two football fields away from that stage where the former president was speaking. Then a U.S. Secret Service counter sniper took him out.
