North Carolina Republican gubernatorial nominee Mark Robinson reportedly called himself a "black NAZI" and said "slavery is not bad" in years-old comments on an online pornographic forum, CNN reports.

Robinson denied the CNN report, which said he referred to himself as a "black NAZI" and expressed support for bringing back slavery more than 10 years ago.

Donald Trump’s campaign declined to comment Thursday on whether North Carolina Lt. Gov. Mark Robinson, whom the former president once described as “Martin Luther King on steroids,” should drop out of the battleground state’s race for governor.
