North Carolina's Republican gubernatorial candidate, Lt. Gov. Mark Robinson, called himself a "Black Nazi" and supported reinstating slavery in comments made on a pornographic website, CNN reported Thursday.

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.

Offensive posts by North Carolina Lt. Gov. Mark Robinson were removed from the pornographic website Nude Africa on Thursday, hours after a CNN KFile investigation revealed a series of inflammatory comments posted on the forum by the controversial and socially conservative Republican nominee for governor of North Carolina.
