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.

He called himself a “Black Nazi,” supported reviving slavery, and bashed Martin Luther King Jr., all on an old porn website where he used to write.

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.
