Gunfire erupted as former President Donald Trump was speaking at his campaign rally on Saturday in Butler County, Pennsylvania, injuring Trump, killing a rallygoer and critically injuring two others. The gunman was killed by the U.S. Secret Service on the scene.Pittsburgh sister station WTAE spoke with a woman who was in the bleachers right behind Trump, whose reaction was caught on camera the moment the gunshots rang out. “You know, it was like ‘boom’ and ‘boom,’ and I turned, and I watched him look and go down, and I was like this is happening, like something serious happened here,” Renee White said.White said this was the 32nd Trump rally she had attended. She traveled 14 hours from North Carolina. White said what happened here doesn't make her nervous about attending another.“No, I'd go to another one in a heartbeat,” White said. “I could walk out in the road and get hit by a car, right? If I go to a rally and I’m somewhere I want to be, and something happens to me, am I dying and doing what I love? Yeah." “For it to happen in Butler County in western Pennsylvania, you just don’t think it would happen,” said Richard Goldinger, Butler County district attorney.Goldinger said he was at a graduation party when someone came out and said the former president was rushed off stage.“Prayers to not only the people that are injured, but the family of the victim that is deceased, and really condolences to this community because sadly it's embarrassing that could happen here,” Goldinger said. Goldinger said it was his understanding that the suspected shooter had no criminal history.
