Former White House spokesman Scott McClellan says his Christian faith motivated him to learn from his mistakes and to write his controversial book about his days as press secretary.
In one chapter, McClellan wrote, "I fell far short of living up to the kind of public servant I wanted to be."
The book entitled What Happened: Inside the Bush White House and Washington's Culture of Deception is already a best-seller on Amazon.com.
Current and former Bush administration insiders have been quick to respond to McClellan's accusations of there being too much secrecy in the White House and that political propaganda was used to support the war in Iraq.
"I can't help but wonder how much of this is Scott's words?," former White House press secretary Ari Fleischer told ABC News. "How much of it is his editors? No matter, what its got is Scott's name on it, and Scott has to stand by it and defend it."
Former White House counselor Dan Bartlett says that many of McClellan's co-workers are puzzled by the book's content.
"Many of us who worked with Scott so closely and worked with him for so many years are quite frankly puzzled and disappointed," Bartlett said.
"He felt burned by the whole Valerie Plame case," explained political commentator Lenny Steinhorn. "He felt like he was hung out to dry on all of that and there is a clear sense that he's not very happy with Vice President Cheney and Karl Rove in this book. To him, those are the people who have lead George Bush astray."
In the past, McClellan has spoken out against memoirs like this. In response to a 2004 book by a former White House counter terrorism czar, he told ABC News that "If someone has concerns, why not raise them sooner?"
Rice: Bush Was Clear on Iraq
Meanwhile, Secretary of State Condoleezza Rice on Thursday rejected all of the allegations in McClellan's book. Rice is attending an international conference on Iraq in Stockholm, Sweden.
She declined to comment on specific charges made by McClellan in his book, but said Bush was honest and forthright about the reasons for the war.
"I am not going to comment on a book that I haven't read," she said. "But what I will say is that the concern about weapons of mass destruction in Saddam Hussein's Iraq was the fundamental reason."
Sticking to My Story
Despite being dubbed a turncoat by some of his closest friends, McClellan is sticking to his guns. He has said he hopes his book will make a difference in the upcoming presidential campaign, according to the Washington Post.
"The White House would prefer I not speak out openly and honestly about my experiences, but I believe there is a larger purpose," McClellan told the Washington Post.
"Ihad all this great hope that we were going to come to Washington and change it. Then we got to Washington, and I think we got caught up in playing the Washington game the way it is being played today," he said.
