POMONA, Calif. (KABC) -- With California's June 7 primary shaping up as a critical battleground in the Democratic primary, Hillary Clinton and Bernie Sanders are scheduling multiple appearances in the Golden State in the next few days.On Saturday, former President Bill Clinton campaigned for his wife in Pomona at Ganesha High School.He was interrupted by protesters, at least one with a megaphone, who began shouting and chanting in the middle of the speech. It was difficult to identify their cause.As the protesters shouted over him, and security escorted them out of the event, Clinton paused and smiled, appearing unruffled."This is not a Donald Trump rally," he said, to big cheers from supporters. "We welcome dissenters and protesters here. This is America."Clinton was introduced in Pomona by Los Angeles County Supervisor Hilda Solis, a former congresswoman who also served in the Obama Cabinet as U.S. labor secretary at the same time Hillary Clinton served as secretary of state.The former president told the crowd of 300-400 that when his wife was nominated by President Obama, she had a request."'I want you to give me two or three of those tech wizards you used to beat me in the primary. And let me put them in the State Department so we can put America onto social media'," the former president said, quoting his wife."She was first major figure to say we are crazy to demonize Muslims. We need Muslims who love freedom and hate terror in America to help us win the battle for social media."On Tuesday, Hillary Clinton arrives to speak at the University of California at Riverside. Her four-day visit is expected to include stops in Los Angeles, Orange County, Salinas and San Jose.Sanders begins a three-day swing through Southern California, starting with a rally in Irvine on Sunday.And on Wednesday, Donald Trump will hold a rally at the Anaheim Convention Center.
