"The mysterious source who gave Americaís foremost journalist, Bob Woodward, a tip-off about the CIA agent at the centre of one of Washingtonís biggest political storms was Stephen Hadley, the White House national security adviser," the Times of London reports.
Think Progress notes that if this report is true, Hadley "was intentionally trying to mislead the press and the public" last week at a news conference "by repeating information from White House officials that he knew to be false."
Earlier, Woodward told Time what made his source come forward.
Update:
Newsweek takes Hadley at his word and speculates former deputy secretary of State Richard Armitage might be Woodward's source.
