According to the Wall Street Journal, Fitzgerald may be investigating the entire White House Iraq Group
in the leaking of Valerie Plame:
Mr. Fitzgerald's pursuit now suggests he might be investigating not a narrow case on the leaking of the agent's name, but perhaps a broader conspiracy. [...] Until now, Mr. Fitzgerald appeared to be focusing on conversations between White House officials such as Mr. Libby and Karl Rove, President Bush's senior political adviser, after Mr. Wilson wrote his op-ed. The defense by Republican operatives has been that White House officials didn't name Ms. Plame, and that any discussion of her was in response to reporters' questions about Mr. Wilson, the kind of casual banter that occurs between sources and reporters. [...] Lawyers familiar with the investigation believe that at least part of the outcome likely hangs on the inner workings of what has been dubbed the White House Iraq Group. Formed in August 2002, the group, which included Messrs. Rove and Libby, worked on setting strategy for selling the war in Iraq to the public in the months leading up to the March 2003 invasion.
This would certainly explain George's twitchy body language
as of late.
