So maybe it was one of those two people who spoke to Fitzgerald not under oath
just out from the NYT
A senior administration official said that neither President Bush himself, nor his chief of staff, Andrew H. Card Jr., nor his counselor, Dan Bartlett, was Mr. Woodward's source. So did spokesmen for former Secretary of State Colin L. Powell, former C.I.A. Director George J. Tenet and his deputy John E. McLaughlin.
A lawyer for Karl Rove, the deputy White House chief of staff who has acknowledged conversations with reporters about the case and remains under investigation, said Mr. Rove was not Mr. Woodward's source.
Vice President Cheney did not join the parade of denials. A spokeswoman said he would have no comment on an ongoing investigation. Several other officials could not be reached for comment.
Remember, there are only so many 'senior administration officials'. I wouldn't have much difficulty believing that Cheney is the ur-leaker. It's been obvious for some time that he's the prime mover in this whole affair. What I find hard to believe is that he came forward to Fitzgerald on his own volition. We shall see. Late Update
