The nonpartisan Congressional Budget Office said millions of Americans would lose health insurance through 2034 under the "one big beautiful bill."

Another 5.1 million people would become uninsured from a combination of expiring Affordable Care Act subsidies and new ACA rules that Trump’s health department proposed, the Congressional Budget Office said. Those coverage losses are separate from the CBO’s official score of the tax bill.
