You could be right, or maybe not. My point is Trump cannot fire leaders in Congress; they do not work for him or under him.
A serious suggestion would be that if Trump vetoes the Omnibus spending bill Ryan and McConnell should resign. That would not be silly. Saying Trump should fire them is just silly.
You are 100% correct. However the Republican office holders in both the House & Senate can get rid of their leaders, by simply voting them out of power in caucus, IMHO, Both Ryan & McConnell should be tossed out SASPO!!!
