"What Trump has done with some success is taken that anger, taken those fears, which are legitimate, and converted them into anger against Mexicans, anger against Muslims," Sanders said, adding that he would use that anger to support things like an increase in the minimum wage.
Sanders said he hopes to use proposals positively for working-class Americans, instead of "dividing us up and having us hate Mexicans or Muslims."
"We need policies that bring us together, that take on the greed of Wall Street, the greed of corporate America," Sanders said.
Sanders shows 34 percent of the Democratic vote, second to former Secretary of State Hillary Clinton's 50 percent.
In a head-to-head General Election match-up between Sanders and Trump, Real Clear Politics shows Sanders with 44.3 percent of the vote to Trump's 42.3 percent.
