Are you aware of how things went down with the Trump documents?
First he was notified that they believed he had documents that he shouldn't and that they wanted them back. He didn't give them back. Then they asked more assertively. That's when Trump started playing musical chairs with hundreds of boxes of documents. They were on the stage at Mar-a-Logo, so he moved a bunch of them into a bathroom. He gave some back and said that was all. Then they told him that was not all, so he moved documents from the bathroom into a storage closet and gave a few more back and said that was all. They told him that was not all and Trump said "yes-huh, it is so" meanwhile he's complaining to people that he shouldn't have to give them back and so he's not gonna. There are discussions with his lawyers that go nowhere and eventually they raided Mar-a-Logo and found hundreds of boxes of documents not being stored even remotely securely. In response to this Trump fell on the ground and throw a little baby tantrum claiming that the greatest injustice in the history of the U.S. had just been done to him.
What Trump did was different. He is being charged with WILLFUL retention of classified documents, because he willfully retained them after being told that he needed to give them back, to the extent that he actively hid them even from his own lawyers so that they reported, believing that it was true, that all documents had been returned.
