You can really tell when Joy knows someone is lying to the panel
Today they had the guest on who is the chief editor (or something like that) at Breitbart. The guy was lying through his teeth about Trump, and Steve Bannon, and just wouldn't give up. Joy kept calling him out over everything he said - as she should. (Sunny was backing her up, and questioning him as well). Poor guy kept trying to keep up the fight, but he lost every time.
I really enjoy when she is the moderator - no one is going to continuously lie to the panel while she's in charge.
