Rover

This makes more sense than the story by Isikoff which claimed that one email got Rove off the hook somehow:

Fitzgerald appeared prepared to indict Rove heading into last week for making false statements, according to three people close to the probe. But that changed during a private meeting last Tuesday between Fitzgerald and Rove's attorney, Robert Luskin. It's not clear precisely what happened in that meeting, but two sources briefed on it said Luskin discussed new information that gave Fitzgerald "pause."

That evening, Fitzgerald's investigative team called Adam Levine, a member of the White House communications team at the time of the leak. An investigator questioned Levine about an e-mail Rove had sent Levine on July 11, 2003 -- the same day Rove discussed Plame with Time magazine reporter Matthew Cooper, according to Dan French, Levine's attorney.

The e-mail, which did not mention Plame, ended with Rove telling Levine to come see him. The investigator wanted details of that conversation, which took place within an hour or so of the Cooper-Rove chat, according to a person familiar with the situation. Levine told investigators they did not discuss Plame.

Part of Rove's defense has been that he was very busy man who simply forgot to tell investigators about his conversation with Cooper. If the e-mail "was exculpatory at all, it was most likely a small piece of a much larger mosaic of information," French said.

A source familiar with the discussion between Rove and Fitzgerald said the Tuesday meeting was about a lot more than "just an e-mail from Levine." He would not elaborate.

Rove remains a focus of the CIA leak probe. He has told friends it is possible he still will be indicted for providing false statements to the grand jury.

"Everyone thinks it is over for Karl and they are wrong," a source close to Rove said. The strategist's legal and political advisers "by no means think the part of the investigation concerning Karl is closed."
