U.S. Special Prosecutor Patrick Fitzgerald has met with a federal grand jury investigating the leak of a covert CIA operative's identity.
Lawyers in the case have said Mr. Fitzgerald may ask the jury to issue charges against President Bush's chief advisor, Karl Rove, and Vice President Dick Cheney's chief of staff, Lewis Libby.
Mr. Fitzgerald has been conducting a nearly two-year investigation into whether someone in the Bush administration blew the cover of a CIA operative (Valerie Plame) in 2003. It is a federal crime to knowingly reveal a covert agent's identity.
The grand jury is scheduled to expire Friday unless extended by a federal judge.
The White House has generally refused to comment on the probe, although media reports indicate Bush administration officials are bracing for at least one indictment.
