Eight years ago, Dan Rather broadcast an explosive report on the Air National Guard service of President George W. Bush. It was supposed to be the legendary newsman's finest hour. Instead, it blew up in his face, tarnishing his career forever and casting a dark cloud of doubt and suspicion over his reporting – and that of every other journalist on the case. This month, as Rather returns with a new memoir, Joe Hagan finally gets to the bottom of the greatest untold story in modern Texas politics, with exclusive, never-before-seen details that shed fresh light on who was right, who was wrong, and what really happened.
