 Two days after an assassination attempt in Butler, Pennsylvania, Donald Trump is in Milwaukee for the Republican National Convention. He spent much of Sunday on the phone with friends, news hosts, and officials. Ohio pastor Daryl Scott said the former president was in great spirits. The FBI say they are investigating the assassination attempt as a potential act of domestic terrorism. They believe shooter Thomas Matthew Crooks acted alone and say he had bomb-making materials in the car he drove. I'm Jennifer King.
