BURLINGAME (CBS SF) – The California Republican Party convention kicked off in Burlingame Friday, as a large group of protesters gathered outside ahead of a planned lunch banquet with presidential frontrunner Donald Trump. Trump arrived at the Hyatt Regency San Francisco Airport at 1333 Old Bayshore Highway in Burlingame shortly after noon. CHP officers pulled off the side of Highway 101. The candidate hopped a fence and entered through the back of the hotel. Trump made reference to his arrival when he spoke to party members. “That was not the easiest entrance I’ve ever made,” the frontrunner said. “It felt like I was crossing the border actually. I was crossing the border, but I got here.”
