That is a bad editting of the video. She slaps his hand away, then looks specifically in the other direction away from him. (Not overtly, but it is obvious)
He then grabs his jacket and straightens it, not knowing what to do. Pride? OUCH.
lmao. First lady publicly doing that to a sitting President during a huge international deal.
No wonder he backed out of some speech after this. His whole fucking world is collapsing. He's probably depressed as fuck. His whole life revolved around impressing people.
