As of yet, there is no indication that the White House has changed it's position on this one:
Bush to Limit Testimony Before 9/11 Panel
WASHINGTON, Feb. 25 — President Bush and Vice President Dick Cheney have placed strict limits on the private interviews they will grant to the federal commission investigating the Sept. 11 attacks, saying that they will meet only with the panel's top two officials and that Mr. Bush will submit to only a single hour of questioning, commission members said Wednesday.
The commission, which has 10 members and is bipartisan, said in a statement that it had also been informed by the White House that Condoleezza Rice, the national security adviser, had rejected its request that she testify in public about the intelligence reports that reached her desk before the Sept. 11 attacks.
Fine. This will make one helluva commercial:
Narrator: "George W. Bush says he's committed to fighting the war on terror. He says he's the kind of leader who will do what it takes to protect us. As long as it isn't incovenient. President Bush actually refused to testify before the independent commission investigating the the tragedy of 9/11. He simply refused. Bill Clinton did. Al Gore did. Bush wouldn't. Cheney wouldn't. Condolezza Rice wouldn't. Bush said he would try to meet with only two of the members of the commission for an hour. Just an hour. He excercises more each day than that. He takes month-long vacations. He attends more fundraisers than any President in history. But when it comes to looking into what it will take to prevent another 9/11 tragedy, President Bush simply could not make time. What do you think of that?"
