LOS ANGELES --Even though he's facing an uphill battle in the remaining Democratic primaries, Sen. Bernie Sanders said he remains confident about his chances in California.
"We think we have an excellent chance to win it," Sanders said in an interview with Eyewitness News.
But if the Vermont Democrat doesn't win the nomination, he said he wants to make sure to tell his supporters not to vote for presumptive GOP nominee Donald Trump.
"He will be a disaster for this country and I will fight as hard as I can to make sure he doesn't get in to the Oval Office," Sanders said.
Elsewhere on the campaign trail Friday, Hillary Clinton was campaigning in Oakland. She was in Monterey Park on Thursday, where her rally was interrupted several times by Sanders supporters.
Clinton's controversy over her use of a private email server is still dogging her. ABC News has learned that the FBI has interviewed top Clinton aides about her email scandal and plans to interview Clinton herself soon.
Trump is facing his own legal difficulties, but he is not expected to testify in the California lawsuit over his Trump University until late November, after the presidential election.
Two more prominent Republicans, Sen. Lindsey Graham of South Carolina and former Florida Gov. Jeb Bush, said they will not support Trump's candidacy.
"I don't think he has the temperament or judgment to be commander in chief," Graham said.
Trump's response: "This guy goes on television, then he talks about 'I know more about the military than Trump, I've been dealing with it for years.' Yeah, for years. That's why we can't beat ISIS."
