Kinda silly. Trump has no Constitutional or political power to fire Ryan or McConnell.
My point is not to speak in defense of Ryan and McConnell, only to point out your recommendation/request/solution is silly.
If POTUS, Trumo vetoes this lunatic budget bill...he will politically destroy Ryan, McConnell, Schumer & Pelosi in one fell swoop!!! We shall soon see, what the POTUS chooses to do.
