“Our problem is that we promised to repeal and replace ObamaCare and we failed," he added.

"We promised to cut taxes and we’ve 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 reelected.”

Graham’s comments come after Trump last week signed an executive order on health care after congressional Republicans repeatedly failed to repeal ObamaCare.

The president last month unveiled a tax framework that would cut the number of individual tax rates and trim business taxes.
