At the very least, theft of government property, but bear in mind that it would be the job of the courts to make the final determination if he is brought to trial. The court of common sense also indicates he is guilty of obstruction of justice for his lack of cooperation in the matter. He's been asked nicely to hand over documents, and it looks like he has gone out of his way to hide them. Whether he turns out to be guilty, common sense enters the picture. Any reasonable person would agree that the government had every reason to be gravely concerned about possible damage caused by the information Trump literally stole. To imply that this search wasn't warranted is absurd. Even if you buy into the questionable argument that Trump declassified what were considered to be highly sensitive TOP SECRET document, the incoming administration has every right and reason to want to assess whether or not that decision to declassify was the result of sound judgement. Based on Trump's past history and character, a reasonable person would have every reason to think it was NOT. So not cooperating with a justifiable government inquiry into THEIR sensitive personal property, which was stolen from THEM, certainly seems like obstruction to me. I think the court of law would be in agreement with the court of common sense.
If you and I have an overdue library book then you and I should be accountable. Now If you have taken a library book without checking it out first then it is called stealing the library book. That is what I would argue if I were a lawyer for we the people. You can not de-classify the library book because it was never yours to begin with. We the people own that library book. If you believe in our Democracy then you have trust in the Judicial branch of government. It is not perfect but it is a lot closer to perfect than the man you believe is above the law...
