I didn't mean specifically this White House, but the fact that Presidents have used executive privilege to shield themselves, and yes Bush HAS used it:
"Because I believe that congressional access to these documents would be contrary to the national interest, I have decided to assert executive privilege with respect to the documents and to instruct you not to release them or otherwise make them available to the Committee."

I thought he might have done so with a couple of his judicial nominees who have worked for the Solicitor General - which would therefore include info about what the govt discussed during certain cases. And .. in those instances - I felt the EP was appropriate.
But .. Clinton used it for everything - and of course the media agreed with him - but now claims BUSH IS SECRETIVE.
