Fitz Knew.

* Leopold - "Fitzgerald Knew Identity of Leaker From Start":

"(fitz) found out the identity of the Bush administration official who disclosed her undercover status to syndicated columnist Robert Novak just two months after the probe began.

But in early February 2004, a month after he started the investigation, Special Prosecutor Patrick Fitzgerald shifted gears and started to build a perjury and obstruction of justice case against (libby & rove).

That month, Justice Department investigators working on the leak case approached a senior official in the Office of Vice President Dick Cheney who had been identified by witnesses as having played a major role in the Plame Wilson leak.

The Bush administration official was given an ultimatum: either cooperate with the special counsel's probe or face criminal charges for his involvement in the leak, attorneys close to the case said.

The senior official decided to cooperate with the investigation and told Fitzgerald that Libby and Rove spoke to reporters about Plame Wilson, the attorneys said.

The official has been identified by attorneys and four current and former White House officials as John Hannah, a senior national security aide on loan to Vice President Dick Cheney from... John Bolton.

Hannah was named Cheney's national security adviser the day Libby was indicted.

The identity of the individual is still unknown. No one in the White House was aware that Hannah was cooperating with the special counsel, the sources said, adding that information Hannah provided to Fitzgerald was instrumental in securing a perjury indictment against Libby. Hannah's attorney did not return numerous calls for comment.

Sources said that Fitzgerald is now preparing the paperwork to present to a grand jury outlining the charges against Rove in hopes of securing an indictment.

The investigation surely would have ended in 2004, the attorneys said, but journalists Fitzgerald subpoenaed went to court to fight the subpoena and the legal challenge delayed the case for nearly a year."
