 Pierre Thomas with us now as well. And Pierre, I wanted to go back to that new reporting tonight that a law enforcement source has told ABC News that a local police officer actually had time to confront the shooter on the roof. This was just moments before he opened fire on the former president. Obviously, this would suggest that authorities might have been just seconds away from possibly stopping all this. But as you reported, the source saying that officer then fell and the suspect was able to then turn back toward the rally and the former president.
