Trump blames the Kentucky Republican for the health overhaul failure. Trump has also worked with Democrats directly on some legislative deals. And Trump's former strategist, Steve Bannon, is working to bulldoze the Republican establishment on Capitol Hill.
Here's what GOP Sen. Lindsey Graham of South Carolina says:
"Mitch McConnell's not our problem. Our problem is that we promised to repeal and replace Obamacare, and we failed. We promised to cut taxes and we have yet to do it. If we're successful, Mitch McConnell's fine. If we're not, we're all in trouble. We lose our majority and I think President Trump will not get re-elected."
