(CNN) -- Tea Party activist Mark Williams says he's done discussing the controversy stirred up by his attack on the NAACP, accusing a fellow movement leader of turning the debate into "a World Wrestling style personality conflict." The National Tea Party Federation, an organization that seeks to represent the Tea Party political movement around the country, has expelled Williams and his Tea Party Express organization because of the inflammatory blog post Williams wrote last week, federation spokesman David Webb said Sunday. In response, Williams announced in another statement on his blog that, "I am refusing all media requests on this" and canceled a scheduled interview on CNN to discuss the controversy Sunday evening, citing a last-minute change in travel plans.
