General Discussion

..classified documents, I don't understand how Trump or Biden left office with a single document, let alone, numerous documents.

I suppose a President and maybe Vice President are given greater latitude and could be allowed to remove a document from the assigned location but one would think they would still have to sign out a document and be expected to return it at some point. And if someone is in charge of keeping up with the signed out stuff, they would be advising the individual of his overdue library book.

In Biden's case, we're talking about files he allegedly took home 6 years ago. I'm close to Joe's age and can't remember all the details of what I did yesterday. But I would bet, if he was shown the documents, he could explain why he had them in the first place.

But, and I'm assuming here, unlike Trump, he wouldn't have wanted or needed to take documents home after leaving office. As someone else noted, there's not enough information available at the moment to draw any conclusions beyond the files getting inadvertently packed in with other stuff.
