I doubt he could show you any video at all of some random reporter but I've seen hours of trump videos and I've never seen him do that motion with his hands anywhere else. I could have missed it but since it's your argument you have the burden of proof so show us. It wouldn't make him much less of a douche bag either way. In a way even for trump it's hard to imagine he'd make fun of a disabled person when his youngest son clearly has issues.
