Rep. Steve King (R-IA) was hammered by CNN's Chris Cuomo for defending Neo-Nazis on Tuesday.

King retweeted a well known Nazi, and refused to take down his tweet even though it promoted hate.

"Here's the thing. When you gave him a platform, and when you have refused to take it down, you have given license to people who share his thoughts. I'm sure your staffers have pointed out to you that on social media you got a lot of ugly people using your name, waving it as a flag as someone who accepts what they are about and ideas because you retweeted this guy," Cuomo said.
