The North Carolina Republican nominee has denied a recent report claiming that he posted graphic sexual messages on a porn site years ago.

According to the CNN investigation, Robinson referred to himself as a “black NAZI,” a “perv” and said “slavery is not bad” in messages posted on a pornography website more than a decade ago.

North Carolina gubernatorial candidate Lt. Gov. Mark Robinson (R-NC) is denying allegations against him, including that he called himself a “black nazi” and used racist, antisemitic, and homophobic slurs on a pornography site’s message board.
