"WASHINGTON, July 11 - Nearly two years after stating that any administration official found to have been involved in leaking the name of an undercover C.I.A. officer would be fired, and assuring that Karl Rove and other senior aides to President Bush had nothing to do with the disclosure, the White House refused on Monday to answer any questions about new evidence of Mr. Rove's role in the matter."
These guys have GOT to know that officially clamming up in the face of serious allegations just feeds the narrative, focuses media attention and gives the story legs. They have GOT to know that.
And that means that they see no other choice.
They're in trouble.
