A policeman shows up on my doorstep. He claims to have the authority to enforce the law. "That's great," I say. "Can I see your badge?" He has to show his badge. Authority must always be confirmed upon request.

There is no such thing an an undocumented declassification. How else can it be established that the thing WAS declassified---and by the proper authority? It is simple to do: date, authority, signature. Declassification removes the document from the requirements of classified control, possession, custody, storage, and destruction.

In point of fact, Trump---himself, personally---did NOT remove the documents from the White House. He had them packed and shipped by GSA. Doesn't matter. If documents are classified, they must be in inventory and stored in a secure container. Period.

This is, for me, the more convincing reason to think that Trump had the documents declassified in the White House. Then, where and how they were shipped afterward would be a non-issue.
