Donald Trump may mock the media because he knows it better than they know themselves. He knows Pooper Cooper likes to play the hysteric gay bully. Trump does not get bullied easily and he deciced that was not going to happen. So Trump “hit back first.”
Towards the end of that video clip Cooper was choking on his words and stuttering he was so intimidated. These media people have no experience with being slapped around. They are so used to doing the slapping. They simply do not know how to react.
