North Carolina Lt. Gov. Mark Robinson announced a lawsuit Tuesday against CNN over its recent report alleging he made explicit racial and sexual posts on a pornography website’s message board, calling the reporting reckless and defamatory.

The lawsuit, filed in Wake County Superior Court, comes less than four weeks after a television report that led many fellow GOP elected officials and candidates, including presidential nominee Donald Trump, to distance themselves from Robinson’s gubernatorial campaign. Robinson announced the lawsuit at a news conference in Raleigh.
