Sources : Bush Knew About Rove's Involvement Two Years Ago

According to the NY Daily News, White House sources say that

Bush was initially furious with Rove in 2003 when his deputy chief of staff conceded he had talked to the press about the Plame leak.

So why hasn't Bush fired Rove? On Cotober 7, 2003, White House Press Secretary Scott McClellan said

If someone leaked classified information, the President wants to know. If someone in this administration leaked classified information, they will no longer be a part of this administration, because that's not the way this White House operates, that's not the way this President expects people in his administration to conduct their business.

So, was Bush initially misinformed? Did Rove hide his involvement?

A second well-placed source said some recently published reports implying Rove had deceived Bush about his involvement in the Wilson counterattack were incorrect and were leaked by White House aides trying to protect the President.

So why hasn't Bush fired Turdblossom? In 2004 Bush stated that he did not know of "anybody in my administration who leaked classified information."

If Bush knew and did nothing, doesn't an argument exist for obstruction of justice charges?
