My guess is the 'librarian' who keeps track of classified documents noticed Biden had many documents that needed to be returned - and that's what started this whole mess. The problem won't be with 'what's found' it'll be with the hundreds of classified documents that are missing - most dealing with China and Ukraine.
That would also explain why Biden was paying private lawyers a thousand bucks an hour to hunt for documents. Those traded to China and Ukraine will never be found.
The excuse? The excuse will be they were accidentally placed in burn bags in the haste and confusion of leaving the White House at the end of the Obama administration.
Good take.
