Hillary Clinton talks immigration reform in California

Hillary Clinton is continuing her efforts to draw contrasts with Donald Trump by stressing her support for immigration reform in a California town close to the Mexico border.

Clinton says, "We have to unify our country." She is criticizing the tone of Trump's campaign, saying: "We shouldn't be insulting one another. We should be looking for common ground wherever we can find it."

Clinton was addressing an enthusiastic crowd at an event center in El Centro, California.

She says Trump can't improve lives, keep people safe or unite the country. And she says she is "really looking forward to debating him."
