A man carrying ammunition and with a gun in his vehicle was arrested Sunday at President Donald Trump’s Los Angeles-area golf course after appearing to monitor security preparations ahead of Trump’s fundraiser there on Tuesday, authorities said. A search of his pickup truck in the golf course car park turned up a loaded 9mm pistol, binoculars and a badge that read “security protection agent,” according to the US attorney’s office in Los Angeles. The sheriff’s department announced the arrest as Trump was preparing to arrive for the Republican National Committee dinner Tuesday at the Trump National Golf Course in Rancho Palos Verdes just south of Los Angeles. “There is no room for error, particularly in light of previous attempts on President Trump’s life.” Last year a jury found a man guilty of trying to assassinate Trump at the president’s Florida country club.
