You fools, and your conspiracies. Schultz obviously didn't send them, so it's a few options I'd go with.
1. It was an idiot Trumpkin trying to convince people, that professional ass covering people, would ever do something that stupidly incriminating. 55% chance
2. It was a Bernie nut that doesn't like Schultz, and he was a little too lit up at the time. 15% chance
3. It was some dolt intern, because someone couldn't bother to ship them. 30% chance
The list leans towards a Trumpkin. Who else would think to add Robert De Niro, but a butthurt Trumpkin? I don't like Schultz, but I refuse to be a daft fool when handling myself, unlike some.
