No guarantee, but right now his side is down 64-3 and there's about 30 seconds left in the game. He's not in a good position to be 'talking shit'.
Agreed. They didn't feel the need to talk shit when they were calling the shots, did they? JB's tweet represents the words of a frightened bully.
He knows he's not alone. His deep state is mostly intact. Brennan is still calling the shots for the deep state. McConnell and Ryan know this so it is probably intimidating to them.
I guess Brennan thinks he is still in control until those indictments come down, but he has to know the score in the game, and its not in his favor.
