Donald Trump was whisked off the stage at a rally in Butler, Pennsylvania Saturday, after gunshots rang through the crowd. Trump could be seen reaching with his right hand toward his neck. He quickly ducked behind the podium as agents from his protective detail rushed the stage and screams rang out from the crowd. The crowd cheered as he got back up and pumped his fist. His campaign later issued a statement saying the Republican candidate was "fine." Law enforcement officials said two people were killed in the incident, including the shooter, and that at least one other person was injured. The shooting is being investigated as an apparent assassination attempt.
