The Scooter Libby trial may be over, but the Valerie Plame case continues -- and signals of a presidential pardon aren't the only thing worth watching.

Attorneys for Plame and her husband, Joseph Wilson, will be back in court in May for a hearing on their civil suit against Libby, Karl Rove, Richard Armitage and Dick Cheney.

In the meantime, House Oversight Committee Chairman Henry Waxman announced today that he will hold a hearing on March 16 to determine whether "White House officials followed appropriate procedures for safeguarding" Plame's identity. Among the witnesses he'd like to call: Patrick Fitzgerald. In a letter to Fitzgerald, Waxman invites the special counsel to meet with him and with ranking Republican member Tom Davis "to discuss the possibility of testifying before the committee and other means by which you can inform the committee about your views and the insights you obtained during the course of your investigation."
