Fitzgerald seeks new grand jury in Plame case

After Bob Woodward's revelation that Valerie Plame's status as a CIA operative was leaked to him well before Libby leaked the name, it stands to reason that Fitzgerald has a new line of investigation.

The questions making the rounds on the blogs is who gave Woodward the name. The concensus is National Security Advisor Stephen Hadley, although the White House is playing its cards close to the vest.

Special prosecutor Patrick Fitzgerald said in court filings that the ongoing CIA leak investigation will involve proceedings before a new grand jury, a possible sign he could seek new charges in the case.

In filings obtained by Reuters on Friday, Fitzgerald said "the investigation is continuing" and that "the investigation will involve proceedings before a different grand jury than the grand jury which returned the indictment" against Vice President Dick Cheney's chief of staff, Lewis "Scooter" Libby.

Fitzgerald did not elaborate in the document. For two years he has been investigating the leak of covert CIA operative Valerie Plame's identity. The grand jury that indicted Libby expired after the charges were filed late last month.

President George W. Bush's top political adviser, Karl Rove, was not indicted along with Libby. But lawyers involved in the case said Rove remained under investigation and may still be charged.
