Washington (CNN) Democratic presidential candidate Beto O'Rourke said in an interview Monday that a campaign event held by President Donald Trump last week "was almost an impromptu Nuremberg rally," implicating Trump supporters with an invocation of Nazism.

"Yes, President Trump is a racist. What we saw in North Carolina last week was almost an impromptu Nuremberg rally, inciting hatred and ultimately, I think implicit in that, is violence against people based on the color of their skin, based on their religion, based on their difference from the majority of Americans," O'Rourke told ABC News. "And it is in keeping the President who describes Mexican immigrants as rapists and criminals, who describes asylum seekers as animals or an infestation , who says that Klansmen are ' very fine people .' It's very clear the path that he is taking us on."

Last week, Trump tweeted, "I don't have a racist bone in my body!"

O'Rourke has previously compared the President's comments on illegal immigration to "rhetoric that you might have heard during the Third Reich."
