I just watched this on CNN this afternoon:

Wolf Blitzer: Does the CIA believe that there was damage done to US national security as a result of Valerie Plame Wilson's name being leaked?

David Ensor, CNN National Security Correspondent: I'm told that in the day that it was leaked there was a quick look done, as there routinely would be, at whether there was damage. Officials simply won't go into the details, but I did speak to one official who did say yes, there was damage, this woman had a long career and she was posing as someone else, and all those people who saw her now know that she wasn't the person they thought that they were dealing with.
