You are the liar. Nothing happened to her that could be considered battery.
You’re both wrong. First, the video that all the Trump supporters kept claiming PROVES that she was lying did nothing of the sort. It showed what looked to be Lewandowski grabbing her, just as she said. Then, all the Trump supporters missed THIS video, conveniently, which clearly shows that it was Lewandowski who grabbed her and yanked her backwards. Her direction of travel immiediately went from moving in the direction Trump was moving to moving backwards, and she stumbled.

Florida 784.03 defines simple battery (or misdemeanor battery) in the following way:
Any actual and intentional touching or striking of another person against that person’s will (non-consensual), or
The intentional causing of bodily harm to another person.
Note that it’s either/or. There doesn’t have to be intent to harm - the only requirement is an intentional act of touching someone against their will. Clearly, Lewandowski touched her against her will, , and although injury is not a requirement for misdemeanor battery, he grabbed her hard enough to leave marks on her arm. It was not in some kind of casual, accidental way, like if he were brushing past her in a crowd. None of the common battery defenses fit what happened in that situation. That’s not to say that he will be arrested for it, but it’s utter BS on the part of Lewandowski and all of his minions to suggest that nothing happened in that encounter, which, if you’ll recall, has been his defense - that he never touched her at all.
