I don't have the stomach to watch it again this early in the day, but I could have sworn that it said "Trump for President Committee" or something like that down at the bottom of the screen there at the end. I think it's pretty obvious this was paid for with leftover campaign funds; it's also pretty damned obvious from the fact that he's still harping on it at every opportunity that Trump is obsessed with the election - still passing out "Electoral Vote Win" maps and bringing it up at bizarre and inappropriate times. As others have pointed out elsewhere, Trump is far more interested in being portrayed as a "winner" than in actually doing the job as President.
