Libby's source for Plame information wasn't Cheney?

Intelligence Correspondant Richard Sale, has a heavily (though anonymously) sourced connection to where Libby first heard about Valerie Plame, and it apparently wasn't from Dick Cheney:

According to the Times account, Cheney told Libby the covert name of the wife of Joseph Wilson, a former U.S. diplomat who had publicly alleged that the administration had mishandled of intelligence relating to Iraq's nuclear weapons programs.

But several former and serving U.S. intelligence officials strongly disputed this. "That is simply not accurate," a very former senior CIA official told this repoter. "Libby's notes on this are misleading and inaccurate or both."

This source, supported by three others, alleged that it was a telephone call from the Department of State that first gave Libby the name of Plame.

The name of the caller? No one is sure. But these sources said that the call defintely came from the State Department office of John Bolton, then the arms control chief of the department.

These same sources alleged that two employees of Bolton, David Wurmser, a virullent pro-war hawk, first told Libby that Valerie Plame had sent Wilson to Niger to attempt to discredit the administration's line on Iraq's nuclear weapons programs.

These same intelligence sources alleged that Wurmser, as Bolton's special assistant, got his knowledge of Plame's classified identity from a colleague in his office, Frederick Fleitz, a CIA officer detailed to Bolton's office from the agency who worked in the CIA's Weapons Intelligence Non-Proliferation and Arms Control Center (WINIPAC.)

"We do not know yet which of the two called," the former very senior intelligence official said.

According to the Raw Story, Wurmser has already been cooperating with Fitzgerald's office - so if he made the call, or the call was made by Fleitz under Bolton's Direction this information may very well be in the hands of the Special Prosecutor.
