They did a damage assessment within the CIA, looking at what this did that Joe Wilson's wife was outed. And turned out it was quite minimal damage. They did not have to pull anyone out undercover abroad. They didn't have to resettle anyone. There was no physical danger of any kind and there was just some embarrassment.
Today we have in the Washington Post:
The CIA has not conducted a formal damage assessment, as is routinely done in cases of espionage and after any legal proceedings have been exhausted. Yesterday, after a two-year inquiry into the leak, special prosecutor Patrick J. Fitzgerald issued a five-count indictment against Vice President Cheney's chief of staff, I. Lewis "Scooter" Libby, for perjury, obstruction of justice and making false statements during the grand jury investigation.
which is it?
