LAS VEGAS (AP) — A federal officer says a man arrested at a Donald Trump rally in Las Vegas told authorities he tried to grab an officer's gun so he could kill the candidate. A complaint filed Monday in U.S. District Court in Nevada charges Michael Steven Sandford with an act of violence on restricted grounds. It cites a report by Special Agent Swierkowski, whose first name was not included, saying Sandford told officers he drove from California to kill Trump and went to a Las Vegas gun range the day before to learn to shoot.
