Trump shooting live updates: Trump praises Secret Service, says Biden call 'nice'

Federal authorities are investigating after former president Donald Trump was shot in an assassination attempt at an election rally in Butler, Pennsylvania, on Saturday.

Secret Service agents swarmed Trump and ducked behind the podium. Blood could be seen on his right ear of Trump as agents surrounded him and led him off the stage to a waiting vehicle to whisk him away.

Trump is "fine," a spokesperson said. The alleged shooter is dead. One spectator was killed and two were hurt, officials said.
