"For more than three years, Mr. Rove and Mr. Libby have been accused, falsely, of being the source of the leak. Mr. Armitage, Mr. Powell, and Justice department officials knew the truth, but said nothing. Clarice Feldman, a Washington, D.C. lawyer, described Mr. Armitage's silence as "inexplicable and perfidious.""

"As most of us have long suspected, the man who told Novak about Valerie Plame was Richard Armitage, Colin Powell's deputy at the State Department and, with his boss, an assiduous underminer of the president's war policy. (His and Powell'sand George Tenet'sfingerprints are all over Bob Woodward's "insider" accounts of post-9/11 policy planning, which helps clear up another nonmystery: Woodward's revelation several months ago that he had known all along about the Wilson-Plame connection and considered it to be no big deal.)"
"Armitage identified himself to Colin Powell as Novak's source before the Fitzgerald inquiry had even been set on foot. The whole thing couldand shouldhave ended right there."
"But Powell and his aides feared the White House would then leak that Armitage had been Novak's sourcepossibly to embarrass State Department officials who had been unenthusiastic about Bush's Iraq policy. So Taft told Gonzales the bare minimum.."

And who is the source for this info? Reportedly, Powell told WH counsel Gonzalez (AG now) that he knew, but he was told to not tell the WH. That is the way things work. And the POTUS stayed protected.
