Its title is The Impeachment Diary: Eyewitness to the Removal of a President. Of it, the distinguished constitutional scholar and Harvard professor, Laurence Tribe wrote: "If ever there was an “eyewitness to history” worthy of the name, James Reston Jr. surely deserves that title. His close-up-and-personal account of the process that drove an American president from office is impossible to put down. To read it is to live it."
