BURLINGAME, UNITED STATES: Hundreds of demonstrators 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.
At one point, several dozen protesters broke through barricades and attempted to storm the hotel where the California Republican Convention was taking place but police, some wielding batons, were able to push them back.

The demonstrators waved banners that read "No hate, no racism, no Trump," "We need a uniter, not a divider" and "Trump is the modern day Hitler." Several carried Mexican flags.
The tense stand-off at the Hyatt Regency, located near San Francisco's international airport, forced the GOP front-runner and his security detail to abandon his motorcade on a nearby highway, hop over a barrier and use a back entrance to the hotel.
"That was not the easiest entrance I've ever made," he told the convention. "It felt like I was crossing the border."
After delivering his speech without incident, he was again escorted out the back entrance.
Some of the protesters lobbed eggs at officers, and at least five were arrested, a police spokesman said.
He added that several demonstrators and police officers suffered minor injuries.
"I am here because I don't like all the bad stuff Trump has been saying lately about immigrants and Latinos," said Eric Lopez, one of the demonstrators. "We are not all like the way he thinks we are."

Jorge-Mario Cabrera, spokesman for the Coalition for Humane Immigrant Rights of Los Angeles (CHIRLA), denounced Trump's rhetoric and said he hoped the real estate magnate would be defeated at the polls.
"The community is sick of being denigrated, disrespected and attacked," he told AFP in a statement. "Nevertheless, our reaction should be to march peacefully, as we have always done, and vote at the polls."
The protest in Burlingame followed similar demonstrations that turned violent late Thursday at another Trump rally in southern California.
Some 20 people were arrested outside the Orange County amphitheater in Costa Mesa during a Trump campaign stopover, which drew a crowd of thousands ahead of the state's June 7 primary.

The demonstrators hurled rocks at passing vehicles and vandalized cars. They smashed at least one patrol car's window and punctured the tires on a police sports utility vehicle, while trying to overturn another police car.
California, which votes on the last day of Republican primaries, is absolutely crucial in Trump's push to secure the number of delegates he needs to win the Republican presidential nomination outright.
