I'm not doubting you, but do you have a link to an old story about this?

So who is Novak's source—and Woodward's source—and why will his identity take the wind out of the brewing storm? One by one last week, a parade of current and former senior officials, including the CIA's George Tenet and national-security adviser Stephen Hadley, denied being the source. A conspicuous exception was former deputy secretary of State Richard Armitage, whose office would only say, "We're not commenting." He was one of a handful of top officials who had access to the information. He is an old source and friend of Woodward's, and he fits Novak's description of his source as "not a partisan gunslinger." Woodward has indicated that he knows the identity of Novak's source, which further suggests his source and Novak's were one and the same.
