Bush's Former Press Secretary Tells All

Scott McClellan blasts Bush in new tell-all book.

Former White House Press Secretary Scott McClellan is opening up in a tell-all book about the Bush administration. From Hurricane Katrina to the war in Iraq, McClellan blasts his former employers.

"History appears poised to confirm what most Americans today have decided: that the decision to invade Iraq was a serious strategic blunder," McClellan writes.

"No-one, including me, can know with absolute certainty how the war will be viewed decades from now when we can more fully understand its impact. What I do know is that war should only be waged when necessary, and the Iraq war was not necessary," he says.

In his 341-page account, titled "What Happened: Inside the Bush White House and Washington's Culture of Deception," McClellan also denounces the response to Hurricane Katrina and the outing of a covert CIA agent by top Bush aides.

McClellan resigned in April 2006 and left a month later, his credibility battered amid the scandal over the leak that Iraq war critic Joseph Wilson's wife, Valerie Plame Wilson, was a covert CIA agent.

Bush was also deceived, "but the top White House officials who knew the truth -- including Rove, Libby, and possibly Vice President Cheney -- allowed me, even encouraged me, to repeat a lie," says McClellan.
