Washington is stirring over a forthcoming novel about the Obama administration, written by an anonymous author who is said to have "vast experience" on the subject of the Obama White House. O: A Presidential Novel, published by Simon & Schuster, will hit shelves on Jan. 25. Besides the title, little else is known about the book. In 1996, reporter Joe Klein anonymously published a similar book about the Clinton White House. Klein has denied that he has anything to do with O. You can bet the race to figure out who is responsible will heat up in the coming weeks.
