Personally I think the leakers name was Joe Wilson.
Joe Wilson had the most to gain.
I think the leaker's name is Joe Wilson, too.
I think it was Lawrence O'Donnell.
Well the leaker could have been Joe Wilson, or some politicized CIA agent who was unhappy with the Bush administration.But the information that the prosecutor is looking for is not the name of source and has very little to do with Valerie Plame. He wants to know the substance of the conversations the leaker had with the reporters on other security matters, possibly leaked information about a raid on a terrorist supporting group that was warned of the raid hours before it took place.
