Art of the Deal co-author predicts Donald Trump is about to resign Donald Trump’s Ghostwriter Tells All Art of the Deal is Donald Trump's signature autobiography and memoir. And no one knows DJT's mentality and philosophy better than the guy who actually wrote the book for Donald. That author, Tony Schwartz, now predicts that Trump will be resigning in the near future, most likely before the end of the year. "Donald has too much pride to allow himself to be 'fired' by the American people, too much pride to be forcefully ousted from office. Instead, he will resign as a means of (partially) salvaging his reputation" says Schwartz.
