That kind of pseudonym is often used by prosecutors to refer to an unindicted co-conspirator, or someone who faces the prospect of being charged. No other administration official is identified in this way in Fitzgerald's indictment.
Arch Pundit noted last week that former Illinois Governor George Ryan, prior to his indictment by Fitzgerald, was referred to as "Individual A" or "Official A" in the indictments of underlings.
From the AP August 27, 2003, Wednesday, BC cycle:
When asked, Fitzgerald would not comment on whether "Official A" was Ryan.
From the Chicago Daily Herald April 3, 2002, Wednesday All
But despite branding two of Ryan's former top aides and his campaign committee as corrupt, Fitzgerald would not say if the investigation will eventually reach Ryan. The vast majority of the corruption uncovered so far happened under his watch when he was secretary of state from 1990 until 1998. The governor has not been accused by prosecutors of any wrongdoing in the past, and Tuesday's indictments did not include him.
"I cannot answer that question," Fitzgerald said when asked about any Ryan involvement. "We cannot discuss people not charged in the indictment."
These news articles along with Fitzgerald's past habits suggest to me that Karl Rove will resign. Either it will be revealed in coming weeks that he made a plea bargain with Fitzgerald to plead guilty to making a false statement to investigators prior to his grand jury testimony in exchange for no jail time and not being charged with perjury before the grand jury, obstruction of justice or with leaking Valerie Plame Wilson's identity or CIA status -- or he will be indicted and fight because Fitzgerald won't agree to no jail time.
I suspect that Rove's 11th-hour disclosures that led Fitzgerald to hold off on indicting him involved something much more significant than his conversation with Adam Levine. If the new information provided by Rove is corroborated in the coming weeks and leads to or cements a charge against someone else, then Fitz may give him what he wants.
But once it is disclosed to the public that Rove either escaped being charged despite his dirty deeds and because of his cooperation against others, or ends up with a false statements charge himself, he is going to have to leave the White House.
I think that's why White House Aides are talking now about whether Rove should stay or go. They know Rove is not walking away from this investigation with a clean bill of health that absolves him of criminal conduct -- regardless of whether he is charged for it. The writing's on the wall.
