"I understand how reprehensible and disgraceful Donald Trump’s positions are, how ignorant they are, how much he is appealing— and I can understand the anger, I surely can," Sanders said at a press conference in Berkeley, Calif., Friday. "The bigotry that is coming from his mouth, the insults to the Mexican community, the Latino community and the Muslim community, and women, and African-Americans, and veterans. I understand the anger.

"But we are not going to defeat Trump, you know, by throwing eggs or getting involved in violence of any kind. We defeat Trump when we stand together as one people and fight for a progressive agenda."

Anti-Trump protests at a Thursday rally in San Jose turned violent as his supporters left the event, with protesters harassing, following and assualting attendees.

When asked Friday about Trump protesters who supported him, Sanders said he didn't want supporters who would turn to violence.
