Who is David Shedd?

From the audio of Scooter's GJ testimony today:

Fitz: Ever talk to a person named David Shedd?
Libby: Have talked to him about a lot of things, but don't recall specifically about Wilson

I decided to find out who is David Shedd. From David Corn's website, October 2003:

In October 2003, I wrote a piece entitled "I Am No Novak" in which I noted that there was one White House staffer, a fellow who was not known to the public, whom the Plame leak special prosecutor ought to interview. This person was then working on the National Security Council staff on nonproliferation matters. What made him special was that prior to that assignment, he had worked with Valerie Wilson at the CIA. I wrote:

This NSC staffer might--I emphasize, might--play a role in the Wilson leak scandal. I know of no reason to suspect he or she is one of the leakers. (A recent Newsweek story referred to this NSCer, but it did not name the staffer.) But perhaps this individual--whom I was told is a CIA officer assigned to the NSC--mentioned Valerie Wilson's CIA connection to one or more White House colleagues during the period in which Joseph Wilson was causing the White House discomfort....Consequently, investigators probing the Wilson leak ought to ask this NSC officer--if they have not already done so--whether he or she talked about Valerie Wilson with anyone in the White House? If the Justice Department investigators can figure out how individuals in the White House came to know about Wilson's wife (if they did), then the gumshoes might be able to find a trail leading to the leakers.

I tried reaching this individual and could not get past the NSC receptionist, who referred me to NSC press spokesman Sean McCormack. He returned my call once, missed me, and then did not return subsequent calls.
I did not name the individual because I did not want to engage in Rove-like conduct. (Hence, the headline of my article.) But now it can be told: the name of this NSC staffer is David Shedd. And he no longer is undercover.

David Shedd was named John Negroponte's associate director and chief of staff. So with Shedd outed, inquiring minds can ask, when the Joseph Wilson story broke, did Shedd tell anyone on the White House staff about Valerie Wilson and what did he say?

What makes the Shedd connection intriguing is the use of Valerie Wilson's maiden name in the Novak column that triggered this scandal. Novak hasn't said how he came to refer to Joseph Wilson's wife as Valerie Plame when at the time she was mostly known as Valerie Wilson. He has hinted--though not said definitively--that he looked her up in a who's who entry for Wilson that listed her by her maiden name. But Larry Johnson points out that people who had worked with Valerie Wilson for years at the CIA--like Shedd--knew her as Valerie Plame. (She had only been married to Wilson for a few years.)
