SAN JOSÉ, United States: Protesters who oppose Donald Trump scuffled with his supporters on Thursday (Friday in Manila) as the presumptive Republican presidential nominee held a rally in California, with fistfights erupting and one supporter hit with an egg. Hundreds of demonstrators blocked a police van and then entered the parking area of the San Jose Convention Center, where the event took place, insulting Trump supporters in their cars and attacking those leaving the rally. A dozen or more people were punched, the Los Angeles Times reported, saying at least one person was hit with an egg. ABC News reported that some protesters surrounded the car of a presumed Trump supporter as it left the convention center garage, shaking the car and smashing its taillight. Crowds had earlier chanted “No hate in our state” and carried signs that read “Dump Trump” as they marched near the convention center. One protester was seen burning an American flag and some supporters were spat on. Several fistfights erupted but were quickly broken up.
