He's got a couple like that. It probably seemed like a big get when he was planning it, and then the day happens and it's more like "well, that was horrible".
I haven't watched it either. It sounds a lot like he gave Snowden a screen... because who knows why... and snowden tried some amateur hour manipulation tactics on him and started in on trying to ingratiate himself to whoever was still willing to watch with his "i'm just a good boi on my way to church, I dindu nuffin, i'm a PATRIOT" shit.
I guess since he livestreams them he can't really just throw them away. And who knows, maybe joe thought it went great.
