Hillary Clinton, Bernie Sanders and Donald Trump are scheduled to appear at several events Friday as they try to gain support from California voters ahead of the state's Tuesday primary.
Former Secretary of State Clinton began her day in Culver City, attending a "Women for Hillary" organizing event at the West Los Angeles College gymnasium.
"We have to -- starting in the California primary on Tuesday -- send an unmistakable message we are stronger together, we are going to work together for a better and fairer nation," Clinton told a cheering crowd.

On Thursday, Hillary Clinton campaigned in San Diego, where she issued a five-point national security plan and said electing Trump would be a "historic mistake."
"I believe he will take our country down a truly dangerous path," Clinton said in a 35-minute speech in Balboa Park.
Among other things, she said Trump picks fights with allies while praising dictators, and claims to know more about the Islamic State than U.S. military leaders.
In response, Trump tweeted: "Crooked Hillary no longer has credibility - too much failure in office. People will not allow another four years of incompetence!" A later tweet criticized what he described as a poor performance reading from a teleprompter.
Speaking at a rally in San Jose Thursday night, Trump called Clinton's speech "sad to watch" and a "phony hit job."
"It was supposed to be a foreign policy speech; it was a political speech," Trump said. "It was a political speech. It had nothing to do with foreign policy."
While Clinton is stressing her concerns about Trump, she is still dealing with her primary race. Clinton needs just 71 more delegates from states voting Tuesday to win the Democratic primary, but is dealing with an increasingly tough fight with rival Bernie Sanders in California, where the Vermont senator is gaining in polling.
On the third straight day of his Bay Area swing, Bernie Sanders made a campaign stop in Palo Alto on Wednesday, to reach out to young techies in the heart of Silicon Valley. On Thursday, Sanders held "A Future to Believe In" rally with Susan Sarandon and Sarah Lee Guthrie in Modesto and a rally at CSU Chico.
