Kos points to this Murray Waass piece:
Vice President Dick Cheney’s former chief of staff, I. Lewis (Scooter) Libby, testified to a federal grand jury that he had been “authorized” by Cheney and other White House “superiors” in the summer of 2003 to disclose classified information to journalists to defend the Bush administration’s use of prewar intelligence in making the case to go to war with Iraq, according to attorneys familiar with the matter, and to court records.
According to sources with firsthand knowledge, Cheney authorized Libby to release additional classified information, including details of the NIE, to defend the administration’s use of prewar intelligence in making the case for war.
Libby specifically claimed that in one instance he had been authorized to divulge portions of a then-still highly classified National Intelligence Estimate regarding Saddam Hussein’s purported efforts to develop nuclear weapons, according to correspondence recently filed in federal court by special prosecutor Patrick J. Fitzgerald
