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.

As Mark Robinson's scandals put his future in doubt in North Carolina, Kamala Harris and other Democrats want one thing: to tie him to Donald Trump.

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.
