Lewis Libby is looking like the one who outed Plame

Valerie Plame, the wife of former ambassador Joseph Wilson, who called the claim of Iraq's obtaining of uranium from Niger false, was outed by a member of the Bush Administration.

In a statement Tuesday, Time [Magazine] said reporter Matthew Cooper agreed to give a deposition after Lewis "Scooter" Libby, Vice President Cheney's chief of staff, personally released Cooper from a promise of confidentiality about a conversation the two had last year.

And from DailyKos on the 23rd:

We know that various administration officials, including Cheney and Bush, have gotten lawyered up. Cheney has retained Terrence O'Donnell, a senior partner in the Washington law firm of Williams & Connelly, while Bush has Jim Sharp, a trial lawer (who does a great deal of criminal defense work) and former assistant U.S. attorney.

John Dean explains why it's significant that Bush & Cheney have obtained outside lawyers.
Looks like Bush will go into the convention having to explain why his people outed a CIA agent.
