Question is, who did it? Someone on PDJT’s staff? Quietly fired? Who was in charge of the video behind him?
It's bad that Trump's people didn't notice it but it almost certainly wasn't something they did.
More likely, it was somebody in the group that he was talking to (Turning Point USA) or, less likely, the hotel that hosted the event (Marriott Marquis).
Turning Point has already fired somebody and said it was due to a rushed image search.
The film tribute was also supposed to have been crummy.
Sabotage or stupidity? Sometimes it can be hard to tell the two apart.
