I believe the analogy raised before "can I wrap the murder weapon in my medical records" applies here.
Also:
"it is the DOJ's job to prove that he didn't do so"
This will be trivial to sarcastic to do.
1) They are labeled classified.
2) The DOJ shows them the nothing that proves they were declassified.
3) Profit.
None of which should happen until Trump takes the stand and says "I declassified them". Neither the DOJ nor the court should entertain Trump's knockoff Chinese tweets as a legal filing.
