The funniest part is the boos were directed at the media, by people that agreed with President Trump,(other than those boos from the media folks, who were reacting to the truth with their customary sophistication).
I’ve never seen anything that stated that. When I heard the talk, the boos were so soft they couldn’t have easily come from the audience but, more likely, from the back of the room where the media was. I assumed it was the media booing, or the people working beside the media.
