The part you quoted is about the incident in Virginia with a male photographer. He did end up on the floor.
Yes. Why is this even in the article unless it is to try and imply the same thing happened to this reporter (Fields) and if both instances were actually the result of interaction with SS agents, why was/is Trump’s campaign manager still being accused?
The point is that the media is trying to make her jostle was a beat down when it was clearly not, and they are trying to imply fault against the campaign for something the SS does.
