The odd thing is that Trump's hand movements don't seem to coordinate with the topic at hand. Most pols manage to make their hand movements correspond with the message, so a slash will accompany emphasis, etc. Trump's got about three moves, the most notable of which is his "okay" gesture, making a circle with his thumb and forefinger. Anyway, Trump has only a few gestures, including that one, and to my eye he uses them seemingly indiscriminately. I've seen him use the "okay/f.u." sign to be pedantic.
