So which is it?

From Reuters:

WASHINGTON (Reuters) - The White House on Thursday asserted “executive privilege” on documents and testimony requested by the Senate and House Judiciary Committees in subpoenas over the firings of several U.S. prosecutors.

“We had hoped this matter could conclude with your committees receiving information in lieu of having to invoke executive privilege. Instead, we are at this conclusion,” Fred Fielding, President George W. Bush’s counsel, wrote in a letter to Sen. Patrick Leahy and Rep. John Conyers.
