McCarthy did. They went anyway.
The question now is why hasn’t McCarthy expelled them from the GOP caucus.
That, of course, is a rhetorical question. He hasn’t done it because he’s worthless, picked from the same mold as Boehner and Ryan.
In a loud flamboyant way at that.
Probably because he's afraid he wouldn't get the 2/3 GOP majority vote he needs to do it.
It would only make him look weaker.
