WASHINGTON (CNN) -- Former White House spokesman Scott McClellan says top administration officials -- including President Bush and Vice President Dick Cheney -- were involved in his "unknowingly" passing along false information about the leak of a CIA operative's identity.
In October 2003, as controversy grew about the leak of Valerie Plame's name, McClellan stood at the White House podium and said that Karl Rove, the president's top political adviser, and I. Lewis "Scooter" Libby, Cheney's chief of staff, had not been involved.
"There was one problem. It was not true," McClellan writes in his new book, "What Happened," which is to be released in April.
The excerpt -- three paragraphs from a 400-page book -- reads in full:
"The most powerful leader in the world had called upon me to speak on his behalf and help restore credibility he lost amid the failure to find weapons of mass destruction in
"There was one problem. It was not true.
"I had unknowingly passed along false information. And five of the highest ranking officials in the administration were involved in my doing so: Rove, Libby, the vice president, the president's chief of staff, and the president himself."
McClellan has not given any specifics about how he believes Bush, Cheney, Libby, Rove and then-Chief of Staff Andrew Card were involved in the dissemination of false information.
Asked about the released excerpt, White House spokesman Scott Stanzel said, "The president has not misled his spokespeople, nor would he."
McClellan, who was White House press secretary from July 2003 until April 2006, said he's still writing the book and that his publisher had highlighted the excerpt to build interest.
Plame, who has filed a civil suit against Cheney, Libby and Rove over the leak, issued a statement saying she was "outraged to learn" that McClellan had confirmed "he was sent out to lie to the press corps and the American public."
"McClellan's revelations provide important support for our civil suit against those who violated our national security and maliciously destroyed my career," she said. (A federal judge dismissed the lawsuit in July, but the case has been appealed.)
Plame's husband, Joe Wilson, said Wednesday the excerpt shows Bush is "out of touch or an accessory of obstruction of justice before the fact and after the fact
Wilson, a former
"I think it would be helpful to have congressional hearings on this matter,"
Just before Libby was to report to a federal prison in July to serve 30 months behind bars, Bush commuted his sentence, although the president stopped short of a full pardon and Libby still had to pay a $250,000 fine.
Rove, who left the White House staff at the end of August, was not charged in the case. His attorney has acknowledged he was one of two sources cited by syndicated columnist Bob Novak, who first disclosed in July 2003 that Plame worked for the CIA shortly after
Former Deputy Secretary of State Richard Armitage has since acknowledged he was Novak's original source for the information that Plame worked at the CIA, although he said the disclosure was not deliberate and he did not know at the time she was a covert agent.
Because deliberately leaking a CIA operative's name can be a federal crime, a special prosecutor, Patrick Fitzgerald, was appointed to investigate the case.
No one was charged in connection with the leak itself; Libby's charges resulted from statements he made during the investigation.
