Well, it sounds like the grand jury might be looking into Rove for perjury and obstrusction of Justice. If that is true, Rove and Libby's time on the hill might be short.

The investigation into the White House leak of a CIA agent's identity is now focusing on whether two top administration officials provided misleading statements to the FBI, it was reported yesterday.
According to press accounts, Karl Rove, the president's chief political adviser, and Lewis "Scooter" Libby, the vice-president's chief of staff, both provided testimony that was later contradicted by other evidence.
...
In an initial round of interviews with investigators, Mr Rove is reported to have omitted to mention that he had discussed the agent's identity with a Time reporter in July 2003, a few days after Mr Wilson had published a highly critical article.
According to a Bloomberg news agency report, Mr Libby testified that he had first heard about Ms Plame from an NBC television journalist, Tim Russert. But according to NBC, Mr Russert denied the claim in his evidence to a grand jury last year.
...
The New York Times yesterday reported that at the time of the leak, Mr Rove and Mr Libby had been collaborating on the administration's response to Mr Wilson's central allegation that President George Bush had misled the American public in his January 2003 State of the Union address.
In that speech, laying out the case for war, the president cited evidence of Iraqi attempts to buy uranium in Niger, west Africa. The claim was found to have been based on forged documents.
...
Leaking the identity of an undercover agent is a serious crime under US law, but prosecutors would have to prove that the leaker was aware of the agent's covert status. However, the investigation, led by federal prosecutor Patrick Fitzgerald, is reported also to be investigating possible charges of perjury and obstruction of justice.
