Protests follow Donald Trump to California Republican convention

Donald Trump, the outsider, made his case to California's Republican establishment on Friday as protesters clashed with police.

Demonstrators swarmed outside the hotel near San Francisco airport, forcing Trump to crawl under a fence to enter the hotel where he met with local Republicanpower brokers and gave a lunchtime speech at the state party's convention. On Thursday night, protesters tangled with authorities and damaged police cars after a Trump rally in Orange County.

Tensions mounted as the Republicanpresidential contest moved into its final stages in one of the nation's most liberal and diverse states. The state party convention amounts to the starting bell in theCalifornia primary, with Ohio Gov. John Kasich appearing later Friday and Texas Sen. Ted Cruz and his new running mate, Carly Fiorina, up Saturday.

During his speech at the convention, Trump called for the party to unify behind him but also issued a veiled threat to its leaders. "There has to be unity in our party," he said. "Would I win could I win without it? I think so because they're going to be voting for me" and not the party, he added.

California's primary usually comes after the party nominees have been decided but this year it looms as a decisive contest that could either clinch the prize for Trump or force him into a contested convention in July.

'It's going to be a free-for-all'

All three candidates are looking to galvanize supporters, sway undecided party members or poach from rival campaigns at the convention. "It's going to be a free-for-all," predicted the state party vice chairman, Harmeet Dhillon.

That label clearly applied to Trump's Orange County rally Thursday night, which filled the Pacific Amphitheatre to its capacity of about 8,000, with many hundreds more turned away.

Protests that stayed mostly peaceful during the event grew in size and anger afterward. Police in riot gear and on horseback pushed the crowd back and away from the arena; one Trump supporter had his face bloodied in a scuffle as he tried to drive away. One man jumped on a police car, leaving its front and rear windows smashed and the top dented, and other protesters sprayed graffiti on a police car and the venue's marquee.

About 20 people were arrested, said the Orange County Sheriff's Department.

On Friday, hundreds of demonstrators pushed to the front doors of the Hyatt Regency in Burlingame before being moved back by police in riot gear. Some protesters infiltrated the hotel building and hung a giant banner reading, "Stop Hate."

The Secret Service led Trump in through a rear entrance to the hotel. Trump joked that as he crawled under a fence to get in, he "felt like I was crossing the border."

Trump's remaining rivals can't beat him in what's left of the primary season. Their only hope is to deny him a majority of delegates heading into the July convention and wrestle for the prize in multiple ballots there.

But questions persist in the party nationally and in California about Trump's electability in the fall and his conservative credentials. So the reception Trump receives from the state's party activists and grassroots organizers will be noteworthy. He rarely speaks to Republican establishment groups, and he rails against what he calls a rigged party system that governs the nomination.

The California convention crowd defies expectation in a state known as a Democratic fortress. There have been pushes toward moderation, but the group leans conservative and favours calls for free markets, tax cuts and smaller government. It's also socially conservative: The state party's platform defines marriage as between a man and a woman, and wants the Supreme Court's affirmation of abortion rights reversed.

Trump has spoken favourably about Planned Parenthood, which provides abortion services. He has warned against cutting Medicare, Medicaid and Social Security, often targets for conservatives who want to slow government spending.

When Trump earlier this month said transgender people should be able to use whichever bathroom they choose, Cruz's campaign released a statement saying Trump was "no different from politically correct leftist elites." The California platform endorses free markets; Trump has long criticized U.S. trade policy and advocated steep tariffs on Chinese goods.

The California primary will award 172 delegates.It takes 1,237 to clinch the nomination.

"It went gangbusters. They attacked me," said Chris Conway, a mortgage broker from San Mateo.

A dozen protesters linked arms to block the road in front of the hotel near San Francisco International Airport, but police had already closed it to traffic. Protesters also draped a large "Stop Hate" banner outside the hotel.

In Southern California, violent demonstrations led to 17 arrests as the Republican presidential contender brought his campaign to conservative Orange County on Thursday.

While Trump held a rally at a fairgrounds amphitheatre, dozens waved anti-Trump signs outside in mostly peaceful protests and traded insults with masses of the candidate's supporters who had lined up to see him. Later in the evening, however, the protests swelled and grew rowdy and spilled into the streets.

Dozens of cars including those of Trump supporters trying to leave were stuck in the street as several hundred demonstrators blocked the road, waved Mexican flags and posed for selfies. Some protesters badgered Trump fans as they walked to their cars in the parking lot.

No major injuries at protest

Police in riot gear and on horseback pushed the crowd back and away from the venue. There were no major injuries and police did not use any force.

Earlier in the evening, a half-dozen anti-Trump protesters taunted those waiting to get into the venue. Trump supporters surrounded one man who waved a Mexican flag and shouted "Build that wall! Build that wall!" a reference to Trump's call to create a barrier between the United States and Mexico to stop illegal border crossings.

Seven shirtless women wearing Bernie Sanders stickers over their breasts entered the square outside the amphitheatre. They said they were protesting Trump's lack of engagement on issues of gender equality and women's rights.

"I feel like he wants to make America great again, but certainly not for women, for the LBGTQ community or for the lower class," said one of the women, Tiernan Hebron, referencing the lesbian, gay, bisexual and transgender community. "He has, like, done nothing to help with gender equality or women's rights or reproductive rights or anything."

Trump has drawn large crowds across the country, with some of his events marred by protests and scuffles. The Pacific Amphitheatre was filled to its capacity of about 8,000 and a couple thousand more were turned away, Orange County Sheriff's Lt. Mark Stichter said.

Earlier this week, a Trump rally in nearby Anaheim turned contentious when his supporters and protesters clashed, and several people were hit by pepper spray. Trump was not present
