Or why Bush would have most likely done exactly the same thing given that he used executive privilege 5 times while Obama has only done so once?
Again, why does that matter? Bush isn't here. If this sort of thing is wrong, then its wrong to do it once, and it's wrong here. If it isn't wrong, then we shouldn't have attacked Bush for it. If it is okay in specific circumstances, can anybody argue why this might fall under that?
Withholding the documents certainly makes me think that the White House was more involved in it than I previously thought.
