If you look at Corey’s head, he does not even turn and it is not clear from the video that he would even remember an “incident” so minor. Also, there is zero evidence where the bruise came from except from statements of the victim who we know is a massive liar, given her absurd exaggerations. All that said, I think the Secret Service should be the ones keeping people from touching their protectee, not the campaign manager. But let’s face it, the definition of assault is absurdly overbroad in the context of the jostling that goes on the real world at events like this (or at a stadium or in a subway etc...).
Whatever, he lied, she has bruises, they have video, and he was arrested.
