Democratic presidential candidate Bernie Sanders on Sunday denied comparing Donald Trump to Hitler after invoking the Holocaust to denounce Trump‘s rhetoric about Muslims.

“Some of you know I’m Jewish,” Sanders said during a town hall in Wisconsin on Saturday. “My father came to this country at the age of 17 from Poland. He came over; other people in his family did not come over. Most people died. Children died. Relatives of my father. So that is in my heart to see what a lunatic can do by stirring up racial hatred. And we’re not going to allow that to take place in this country.”

During an appearance on ABC’s “This Week” program, host George Stephanopoulos asked Sanders if he was comparing Trump to Hitler? “Oh no, no, there’s nothing to do — no, that’s not right,” he responded. “What I talked about there was a Muslim woman there next to me, and she is telling me that, what is true, is that people in the Muslim community are very fearful now. And what I was saying is I’m going to do everything that I can to kind of stop those Islamophobic attacks so that kids in this country who happen to be Muslim are afraid.”

“No, I did not compare Trump to Hitler. But I will do everything that I can to stop this type of hatred and hate talk that we are hearing,” Sanders added.
