Subject: Re: Trump on Tape w/ Classified Docs
The President probably can set up whatever procedure he chooses, via Executive Order - or even informally. But it would have to be something, some externally verifiable indicia that the President has actually acted. That the status of the documents that have previously been classified has now been changed - that someone has received some instruction from the President that the classification has been lifted.

Okay, so
*Trump has the power to declassify
*The procedure isn't clear, but the President determines the procedure.
