>> Violent clashes between police and protesters in the streets of San Diego, outside a Donald Trump rally. Police say they arrested 35 people outside an event Friday that drew nearly 1,000 demonstrators. In many cases, law enforcement had to intervene when Trump's supporters and opponents started trading blows.>> I love you San Diego, get out and vote.
>> Inside, the presumptive Republican presidential nominee addressed nearly 10,000 supporters, reiterating his anti-immigrant stance and promised to build a wall with Mexico. Several protestors were ejected from the event.>> Get them out! Get them out!>> Trump is criss crossing California in an effort to put pressure on Republicans to support his divisive candidacy.
Reuters correspondent Emily Stevenson.>> Trump seems to be doing these rallies in places where he's gone after Republicans who are leaders or the Republicans who are mayors of these towns who have not endorsed him. On Friday, Trump was in Fresno, California, where the mayor backed Republican John Kasich, in San Diego where the mayor, another Republican, has said he will not endorse Trump.
So Trump seems to be kind of spoiling for these fights, and this is part of his effort on this western swing to convince people that he is not a regular Republican. He claims he could put 15 states in play in the general election.>> Are you ready?>> A Republican hasn't won California in the general election since the 1980s.
But Trump is saying he can change that.>> I wanna make a big play for California. Should I?>>
>> I really believe we're gonna win it. I think we have a real chance to win it.
San Diego's population is nearly a third Hispanic. Many residents live and work on opposite sides of the border.
California is home to the largest Latino population in the US. The scene in the streets, now familiar at Trump rallies in California, opponents waving Mexican flags, confronting police in riot gear, trying to wash pepper spray from their eyes and faces.
