Lurkinanloomin, you are 100% correct. However, if a sitting president decides he cannot work with a member of the House there are ways he can let people know. Ryan would not last. Ryan will do everything in his power to subvert Trump while claiming he is working for the president. That is the type of personality he has. A despicable worm.
I agree that Ryan is attempting to subvert the Trump agenda, but President Trump says he has full confidence in him and attacks the Freedom Caucus instead.
