• Greg Smith, interviewed by the BBC, said he told police officers about a man with a rifle on the rooftop three to four minutes before the shooting took place. Smith said: "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."After the failed assassination attempt on former Pres. Donald Trump at a campaign event on Saturday, the Secret Service and other law enforcement agencies are facing questions about how a shooter armed with an AR-style rifle was able to get to a rooftop so close to where the presumptive Republican nominee for president was speaking.
