The great thing about the White House statement is that it doesn't accuse Lockhart of being involved with the forgeries. It goes to the far more easily provable, but very damning, fact that CBS was coordinating with Kerry's campaign.
Expect Lockhart to resign tomorrow. Also, expect a similar announcement from Mapes. They will both fall on their swords for the real conspirators, Kerry and Rather. Hopefully, the White House, with help from FR, will keep the heat on.
