Republican presidential candidate Ron Paul abruptly ended an interview with CNN’s Gloria Borger yesterday after she asked him about racist newsletters published under his name in the 1980s and 1990s.

When Borger questioned Paul about profit he reportedly made from the newsletters, some of which contained prejudiced statements about African Americans and conspiracy theories about AIDS, Paul protested that he “never read that stuff.”

“I was probably aware of it ten years after it was written,” he said. “It’s been going on 20 years that people have pestered me about this and CNN does it every single time. So when are you going to wear yourself out?”

Borger responded that the newsletters, whose titles included Ron Paul’s Political Report and Ron Paul’s Freedom Report and were written in the first person, were “pretty incendiary.”

“Because of people like you,” Paul said, before removing his microphone and walking off the interview.
