Something doesn’t make sense about this video.
At :57 it distorts & it looks like it’s when he is just getting out of the bus.
Then it clears up and a little later on, it shows him getting out of the bus again.
The caption as the distortion starts says its how the Washington Post got it, that it came that way.
You have a very valid point. Trump may have said something more sincere and whoever produced the tape edited it out.
