“A man with a rifle was seen on a rooftop minutes before shots were fired at a Donald Trump rally in Pennsylvania,” a witness told the BBC.
“Greg, the witness, said the man had crawled on top of a building just outside the event in Butler County on Friday evening.”
“He said he pointed the gunman out to police.
”Said the witness: “I’m thinking to myself ‘Why is Trump still speaking, why have they not pulled him off the stage’… the next thing you know, five shots ring out.”
