WASHINGTON (AP) – For the better part of two years, the word coming out of the Bush White House was that presidential advisor Karl Rove had nothing to do with the leak of a female CIA officer’s identity and that whoever did, would be fired.

But Bush spokesman Scott McClellan wouldn’t repeat those claims Monday in the face of Rove’s own lawyer, Robert Luskin, acknowledging that the political operative spoke to Matthew Cooper of Time magazine, one of the reporters who disclosed Valerie Plame’s name.

McLellan repeatedly said he could not comment because the matter is under investigation.

When it was pointed out he had commented previously even though the investigation was ongoing, he responded: “I’ve really said all I’m going to say on it.”

Democrats jumped on the issue, calling for the administration to fire Rove, or at least to yank his security clearance.

One Democrat pushed for Republicans to hold a congressional hearing in which Rove would testify.

“The White House promised if anyone was involved in the Valerie Plame affair, they would no longer be in this administration,” said Senate Minority Leader Harry Reid.

“I trust they will follow through on this pledge. If these allegations are true, this rises above politics and is about our national security.”

The investigation into the 2003 leak had largely faded into the background until last week, when New York Times reporter Judith Miller went to jail rather than reveal who in the administration talked to her about Plame.

Cooper also had planned to go to jail rather than reveal his source but at the last minute agreed to cooperate with investigators when his source – Rove – gave him permission to do so.

Cooper’s employer, Time Inc, also turned over Cooper’s email and notes.

One of the emails was a note from Cooper to his boss in which he said he had spoken to Rove, who described the wife of former US ambassador and Bush administration critic Joe Wilson as someone who “apparently works” at the CIA, Newsweek magazine reported.

Within days of the July 11, 2003, email, Cooper’s byline was on a Time article identifying Wilson’s wife by name – Valerie Plame. Her identity was first disclosed by columnist Robert Novak.

The email did not say Rove had disclosed the name. but it made clear that Rove had discussed the issue.

That ran counter to what McClellan has been saying. For example, in September and October 2003, McClellan’s comments about Rove included the following: “The president knows that Karl Rove wasn’t involved,”; “It was a ridiculous suggestion”; and “It’s not true.”

Reporters seized on the subject Monday, pressing McClellan to either repeat the denials or explain why he can’t now.

“I have said for quite some time that this is an ongoing investigation and we’re not going to get into discussing it,” McClellan replied.

Asked whether Rove committed a crime, McClellan said, “This is a question relating to an ongoing investigation.”

Rove declined to comment Monday and referred questions to his attorney. Last year, he said, “I didn’t know her name and didn’t leak her name.”

The Rove disclosure was an embarrassment for a White House that prides itself on not leaking to reporters and has insisted that Rove was not involved in exposing Plame’s identity.

The disclosure also left in doubt whether Bush would carry out his promise to fire anyone found to have leaked the CIA operative’s identity. Rove is one of the president’s closest confidants – the man Bush has described as the architect of his re-election, and currently deputy White House chief of staff.

Rove’s conversation with Cooper took place five days after Plame’s husband suggested in a New York Times op-ed piece that the Bush administration had manipulated intelligence on weapons of mass destruction to justify the invasion of Iraq.

Wilson has since suggested his wife’s name was leaked as retaliation.

Luskin, Rove’s lawyer, said his client did not disclose Plame’s name.

Luskin declined to say how Rove found out that Wilson’s wife worked for the CIA and refused to say how Rove came across the information that it was Wilson’s wife who authorised his trip to Africa.

Rove’s lawyer says his client has done nothing wrong.
