 with Trump supporters ducking for cover, scrambling to help. We talked to one man earlier today who was a physician. This was his very first Trump rally. He told me that he was near the person who was ultimately shot and killed. He rushed in to try and help. He said ultimately it was too late. He left here not too long ago after talking to the FBI. So we know that they're continuing these rounds of interviews with the eyewitnesses that saw exactly what unfolded here just hours ago.
