***UPDATE***
Think Progress reported this afternoon that White House spokesperson Dana Perino told reporters Friday during a press conference that the White House could possibly stop McClellan from testifying before Congress:
QUESTION: Could the White House block him from testifying, if he wanted to testify? Or how does that work?PERINO: Conceivably?
QUESTION: Yes.
PERINO: Hypothetically, which I'm not supposed to answer a hypothetical, yes, I think so. The law would allow for that. But by saying that, I'm not suggesting that that's what would happen or not happen.
McClellan himself told CNN's Wolf Blitzer Friday that he'd be "glad" to testify about the Bush White House. That and he doesn't see himself apologizing to George Bush any time soon:
"I don't need to ask for any forgiveness from him because my comments are sincere and honest ... it was tough getting to the conclusions I drew, but they were absolutely the truth from my perspective."
The Politico says House Judiciary Chair John Conyers is considering a hearing on the McClellan book to determine the real facts surrounding the Valerie Plame scandal.
House Judiciary Committee Chairman John Conyers (D-Mich.) said today that he plans to begin discussions with former White House press secretary Scott McClellan regarding his participation in a congressional hearing.
"I find Mr. McClellan's revelations about attempts to cover-up the Valerie Plame leak extremely troubling. Particularly disturbing is McClellan's assertion that he was specifically directed by Andy Card to 'vouch' for Scooter Libby after the investigation had begun, which, if true, could amount to obstruction of justice beyond that for which Mr. Libby has already been convicted," said Conyers.

Florida Congressman Robert Wexler wants Scott McClellan to testify before Congress on the events in his book.
Former Bush spokesman Scott McClellan should testify under oath on Capitol Hill about his explosive new book in which he sharply criticizes his old boss, a Democratic congressman said Friday.
Rep. Robert Wexler, D-Florida, said McClellan, who served as the president's press secretary before leaving the White House in 2006, would be able to provide valuable insight into a number of issues that the House Judiciary Committee is investigating.
