Kabuki.
I am old enough to remember Trey Gowdy and Darrell Issa....
So I wouldn't call this Kabuki theatre. Now you can see why Trump didn't fire him. The brilliance of Trump is that he gives his enemies the rope to hang themselves by not silencing them so that everyone can see what's going on.
Just another round of useless tit for tat that will never amount to anything.
