Wouldn't it be funny if he took the nuclear codes with him though. Not that it would be any real risk.

Big if true section :
Apparantly rumor says there might have been TS (Top Secret) and SCI (Secret Classified Information) documents in Trumps residence which the FBI found and seized now. And it seems SCI Documents are the kind of documents that would tell you who killed Kennedy or where the Aliens are or something, in other words even more than Top Secret. Speculation is, Trump "declassified" them before he took them with him. But I doubt it would be that simple. Another rumor says he stored them in his pool house.
