North Carolina Democratic Attorney General Josh Stein declined to debate Republican Lt. Gov. Mark Robinson as the Republican faces scrutiny over salacious comments he allegedly posted online. Stein and Robinson are engaged in a battle to become North Carolina’s next governor this fall.

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'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.
