IMO the rickroll is the big “tell” that this speech was tampered with on purpose to take away from the other speeches last night. Whoever did this got a little too cute.
HOWEVER, if Trump didn't do it..it is a telling sign.
There are only two things here.
Either Trump did it.
Or he didn't.
If he didn't, heads need to roll because he has a traitor in his midst
Trump is in an all out war against both sides of the aisle. It is LUDICROUS to think this possible sabatoge should just be ignored
