 Trump is safe and on the mend after he was rushed off the stage by Secret Service. Ben Masur told KDKA that he saw the shooter sitting on a rooftop around 200 to 250 yards from where Trump was speaking. Another witness, Ryan Knight, said he heard someone said, Oh God, he had a gun. And when he looked up, he saw a man on top of a building with a gun aimed at Trump. Knight said he dropped to the ground and when he looked back up, he saw the shooter get killed by the Secret Service agents. The FBI says they have yet to identify a motive. I'm Lisa Taylor.
