Reeling from last week’s stinging defeat in the Senate, Donald Trump took up his online bully pulpit over the weekend to urge Republicans not to give up on passing a health-care bill. “Unless the Republican Senators are total quitters, Repeal & Replace is not dead! Demand another vote before voting on any other bill!” the president wrote on Twitter. But despite Trump’s taunts and threats, his party’s leaders are showing no indication that they’re interested in returning to the divisive issue before the end of the summer. “Until somebody shows us a way to get that elusive 50th vote, I think it’s over,” John Thune, the third-ranking Republican senator, told Politico. “Maybe lightning will strike and something will come together but I’m not holding my breath.”

After seven years of railing against Barack Obama’s signature legislation, the Republican Party saw its best opportunity to dismantle the sprawling 2010 law go up in smoke when John McCain unexpectedly joined Lisa Murkowski and Susan Collins in opposing Mitch McConnell’s “skinny” repeal bill, the Senate majority leader’s last-ditch attempt to restart debate after a tumultuous series of failed votes. After months of struggling to bridge the divide between conservative and moderate Republicans, McConnell conceded, “It’s time to move on.” A bipartisan coalition in the House is already discussing plans to stabilize the Obamacare exchanges instead.

Senate Republicans, meanwhile, look ready to move on to tax reform. “I think it’s time to move on to something else. Come back to health care when we’ve had more time to get beyond the moment we’re in—see if we can’t put some wins on the board,” Roy Blunt of Missouri told The Washington Post. “There’s just too much animosity and we are too divided on health care,” Senator Orrin Hatch said in an interview with Reuters. “I think we ought to acknowledge that we can come back to health care afterwards but we need to move ahead on tax reform.”

Trump is not on the same page. “In the White House’s view, they can’t move on in the Senate,” Budget Director Mick Mulvaney said during an interview on CNN’s State of the Union on Sunday. “You can’t promise folks you’re going to do something for seven years, and then not do it.” But Republicans seem collectively fed up with the president‘s pronouncements on a subject he has demonstrated little mastery of. “I don’t think [Mulvaney’s] got much experience in the Senate, as I recall,” Senate whip John Cornyn shot back at Mulvaney, a former South Carolina congressman. “And he’s got a big job. He ought to do that job and let us do our job.” Hatch, for his part, has volunteered to inform the Trump administration that it is time to shift focus. “I’m going to be one who does that,” the Utah lawmaker told Reuters, adding that he expected McConnell and Speaker of the House Paul Ryan to do the same.
