Joan Rivers was promoting her new book Diary of a Mad Diva, when the 81 year old comedian stormed out of a CNN interview Saturday because she felt anchor Fredricka Whitfield’s line of questioning was too “negative.” In a statement, Joan defended her actions, saying, “The CNN interviewer was a news reporter and not an entertainment reporter. She did not seem to understand we were talking about a comedy book and not the transcripts from the Nuremberg Trial.”
