Trump cracks the whip on Obamacare, fueling GOP momentum | 17 March 2017 | Rep. Robert Aderholt was among a bloc of conservatives threatening to tank the Republican health care plan when President Donald Trump summoned him to the White House on Friday. At a meeting with more than a dozen other lawmakers wary of the legislation, Aderholt told Trump he was worried that elderly Americans would be hit with huge premium increases. But Trump prevailed on him, looking Aderholt in the eye and promising: "These are my people and I will not let them down. We will fix this for them." Aderholt switched his vote in favor right then and there.
