He took top secret documents when he left the white house. They don’t belong to him, they’re meant to be secured in the library of congress or something. Anyway, librarians tried to get them back, he said no, did a bunch of illegal shit (including flashing them around people he wanted to impress) so FBI got involved, raided his place, found more secret documents, special prosecutor was appointed who took ages really nailing the iron clad case together. Now he been arraigned in court facing federal charges. Because Trumps a dumb shit.
