Excuse me .. there is NO RECORD of President Bush EVER using "executive priviledge" - at least not that I know of. Clinton did it all the time - but I cannot remember a single time Bush has done that.
So if you have evidence .. bring it on!
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."

The White House has used executive privilege in regard to VP Cheney's energy task force meetings. Some folks wanted to know what was said in private meetings between oil execs and the VP. The White House won before the SC on this issue. If there were evidence of some criminal wrongdoing, then there would be an issue, but folks just wanted to know everything about the meetings.
Bubba used executive privilege to thwart investigation of his "private sex life." The courts did not favor him. He had to comply with Ken Starr's subpoenas on multiple occasions even though he claimed executive privilege. Some things are private.
