North Carolina's Republican candidate for governor promised to stay in the race on Thursday after CNN reported that he once called himself a "black NAZI!" and proposed bringing back slavery in comments posted on a pornography website.

The CNN report describes a series of racial and sexual comments Robinson allegedly posted on the message board of a pornography website more than a decade ago.

North Carolina Republican gubernatorial nominee Mark Robinson has vowed to remain in his race despite a CNN media report about comments it says he made on a website.
