 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 countersniper took him out. Investigators haven't said what his motive was yet.
