BURLINGAME, United States: Hundreds of protesters jostled with police in riot gear Friday outside a California hotel where Republican presidential frontrunner Donald Trump was to give a speech, forcing the candidate to duck into a back entrance. Protesters broke through barricades set up around the hotel near San Francisco’s international airport where the California Republican Convention was taking place. Police guarding the entrances were able to stop them from entering the hotel. Some protesters lobbed eggs at officers, and news footage showed a few protesters being dragged away by police after Trump’s speech ended. The tense protest in Burlingame follows similar demonstrations that turned violent late Thursday at another Trump campaign rally in southern California.
