"Because of the rise of Trumpism, if you like, suddenly a lot of the racism that had been kind of pushed down is now popping up again," Sanders said at a forum with Asian-Americans and Pacific Islanders in California Wednesday.

Sanders said the country has a history of dealing with racism and continued to criticize Trump for the role he's played in intensifying the issue.

"I have talked to Muslims who tell me that their children are now afraid to walk the streets and people are fearful" for their lives, Sanders said. "This cannot and must not be allowed to go on in the United States of America."

Trump has faced backlash for calling for a temporary ban on Muslims entering the country and for his proposal to build a wall along the Mexican border.

Some Democratic leaders have called the presumptive GOP nominee racist, and many have condemned his rhetoric.
