Around 7.30pm local time, approximately 1,000 demonstrators clashed with Trump supporters leaving the arena in San Jose where Trump spoke.

But earlier in the afternoon, hundreds of protesters, mostly Latino students from nearby colleges and high schools, as well as a large contingent of union members, had gathered peacefully outside the convention center, chanting their anger at Trump and at times jeering at his supporters as they passed by.

“I have family members who are illegal immigrants and they’re scared,” said Monse Lozano, 18, of San Jose. “I’m a citizen and I can’t do much for them.”

Demonstrators waved Mexican flags and chanted in Spanish and English. One man yelled at Trump supporters entering the arena, “Somos mad Americanos que ellos.”

But as Trump supporters began trickling out of the venue, the tenor of the crowd shifted. One woman in Trump apparel taunted the crowd before retreating into the nearby Marriott hotel, prompting a shift in the mood of the crowd.

As more Trump supporters began leaving the arena, bands of mostly young men began chasing, and in some instances hitting, them. The protest grew chaotic.

Some protesters set red “Make America Great Again” hats on fire. Some burned small American flags.

At one point, a group of protesters entered the convention center parking lot, where Trump supporters were attempting to leave. Some banged on cars, yelling at the occupants. As protesters attempted to surround a Corvette, the driver gunned the engine, almost hitting several people and sending the protesters running.

As night fell, and riot cops began to move in on the protesters, Martha Garcia, a student from San Jose, expressed disappointment in the violence.

“It’s sad to see San Jose representing like this. Trump is the one igniting the hate. You can’t fight fire with fire,” she said.
