The documents may contain evidence of crimes... not Trumps but others. He preserved the chain of evidence through classification of the information. Just like evidence there is always a chain of custody for classified materials. Perhaps this was his way of getting around the FBI and maintaining a side chain until he could get it Into the right hands. Who else might be conducting independent investigations? Durham, huber. If not them maybe something of its own not yet revealed.

Based on trumps usual 4d chess moves I go with this one. Also had many ultimate results. Biden getting the blame being the best.
