Shock jock DON IMUS is facing a multi-million dollar lawsuit from advertisers on his former radio show who claim he insulted a book the company was trying to promote. Flatsigned Press Inc., a book publisher based in Nashville, Tennesse, has accused Imus of badmouthing the company by calling its radio commercials for a book by the late President Gerald Ford "cheesy". The lawsuit, which is asking for over $4 million (GBP2 million) in damages, claims the star told listeners to his Imus In The Morning show on New York radio station WFAN that the publishers "have been waiting for (Ford) to croak (die) so they can unload these (books)". The court papers also state that the DJ's "libelous and disparaging statements" irreparably damaged sales of Ford's book - a story about the Warren Commission's investigation into the 1963 assassination of President John F. Kennedy. As well as $4 million (GBP2 million) in compensatory damages for breach of contract, libel and malice, the suit is also asking for another $59,000 (GBP29,500) for money spent on a newspaper advert that ran after the commercials on Imus's show. Imus was fired from WFAN last year (07) after making a racially charged remark about the Rutgers University women's basketball team and now has a syndicated show on WABC.
