House Republicans unveiled the cost-saving centerpiece of President Donald Trump's “ big, beautiful bill ” late Sunday, at least $880 billion in cuts largely to Medicaid to help cover the cost of $4.5 trillion in tax breaks. Tallying hundreds of pages, the legislation is touching off the biggest political fight over health care since Republicans tried to repeal and replace the Affordable Care Act, or Obamacare, during Trump's first term in 2017 — which ended in failure. While Republicans insist they are simply rooting out “waste, fraud and abuse” to generate savings with new work and eligibility requirements, Democrats warn that millions of Americans will lose coverage. A preliminary estimate from the nonpartisan Congressional Budget Office said the proposals would reduce the number of people with health care by 8.6 million over the decade. “Savings like these allow us to use this bill to renew the Trump tax cuts and keep Republicans’ promise to hardworking middle-class families,” said Rep. Brett Guthrie of Kentucky, the GOP chairman of the Energy and Commerce Committee, which handles health care spending. But Democrats said the cuts are “shameful” and essentially amount to another attempt to repeal Obamacare. “In no uncertain terms, millions of Americans will lose their health care coverage," said Rep. Frank Pallone of New Jersey, the top Democrat on the panel. He said "hospitals will close, seniors will not be able to access the care they need, and premiums will rise for millions of people if this bill passes." As Republicans race toward House Speaker Mike Johnson's Memorial Day deadline to pass Trump's big bill of tax breaks and spending cuts, they are preparing to flood the zone with round-the-clock public hearings this week on various sections before they are stitched together in what will become a massive package.
