"As to classified status, the WH has the authority/right to override that, I believe"
Just for emphasis (not to you redgirl), ALL, top-to-bottom, right-to-left, backwards-and-forwards classification authority extends from the President, down. There is no higher authority than the President in either the military or the federal government.
Declassification authority is identical, and in both cases, the "process" for classifying or declassifying anything and everything is precisely what the President says it is (or isn't). The President can declassify anything at the snap or his fingerrs, or force an agency (say, NORAD) to adhere to rigorous classification processes.
I thought so.
