Looks like his artist loft. Notice the pixalated “keep on trumping” art work in the background.
The only conclusion I can come to re: the Hunter mickey mouse watch and Keep on Trumpin is that he spilled the beans in return for some kind of reduced punishment. Remember when Bitem first got in, there was a video of Bitem signing something and audio of a man saying something about a plea bargain? It was even up on official White House youtube or other channel for a while. I watched it several times.
