Man, I'm starting to wonder if every president has had personal possession of classified documents.

Another thing to think about is the sheer number of things that warrant some level of classification. There’s got to be so, SO much that would be classified to one degree or another. 

I’m just guessing, but I don’t think these are the “top secret - eyes only” sort of things, but more the “this tangentially relates to something that could reveal the existence of other classified information if carefully analyzed by a sophisticated agency” sort of things.
