I don't see this man derailing anything the GOP wants to pass. Does he really want Trump calling him out? I think trump is going to be increasingly upset about how many gridlocks are in congress. They won't be able to blame obama or the democrats anymore. We will see a lot of infighting with trump and congress if they gridlock any of his plans. They probably know this and are just gonna give him what he wants as long as he backs their agenda as well and they don't try to impeach him.
