Asweeping bill that's at the center of Republicans' efforts to deliver on President Donald Trump's second-term agenda hit a major roadblock on Friday.

Trump was not happy.

“We don’t need ‘GRANDSTANDERS’ in the Republican Party,” the President posted on Truth Social minutes before a handful of GOP hardliners voted against his “big, beautiful bill” at a key House Budget Committee meeting, effectively stalling the legislation from advancing.

The measure would extend Trump’s 2017 tax cuts and increase spending on the military and border security, offset in part by cuts to Medicaid, food stamps, and subsidies for clean energy. House Speaker Mike Johnson has struggled to craft a bill that slashes enough spending to satisfy right-wing members of his party without losing support from GOP moderates, who are wary of cutting too much from widely used safety-net programs.

Republican leaders had been hoping to push the bill through the House before a Memorial Day recess, though that timeline appears less probable after Friday’s failed vote in the Budget Committee—one of the final stops before it can reach the House floor.

Five Republican fiscal hawks on the committee joined with all Democrats in voting against the bill, with the GOP holdouts expressing concerns that the bill doesn’t cut Medicaid spending enough and takes too long phasing out the clean energy tax credits passed as part of former President Joe Biden’s Inflation Reduction Act. They argued that the way the bill front-loads tax cuts in the next few years but delays spending cuts until later is fiscally reckless.

“This bill falls profoundly short. It does not do what we say it does with respect to deficits,” Texas Rep. Chip Roy, one of those holdouts, said during the markup.

South Carolina Rep. Ralph Norman, another one of the holdouts, said he was “very disappointed” with the bill: “Sadly, I’m a hard no until we get this ironed out.”

Top GOP lawmakers are expected to continue private talks with the White House and reluctant Republicans over the weekend to figure out a path forward on Trump’s signature legislation. They are using a process known as budget reconciliation to allow Republicans to push the measure through the Senate with a simple majority, rather than the two-thirds support they would need to avoid a filibuster. Assuming Democrats remain united against the bill, Republicans can afford to lose no more than three votes in either the House or the Senate.

Even if the bill makes it through the House, Republican Senators are expected to make their own changes to it, which both chambers will then have to reconcile.

Here are the main sticking points for Republicans on Trump’s “big, beautiful bill.”

Medicaid cuts
For months, Democrats have condemned the bill’s health care provisions as a disaster for the country. More than eight million Americans are expected to lose insurance coverage if the bill becomes law—an outcome some Republicans fear will kill their chances in the 2026 midterms.But that isn’t stopping some fiscal conservatives from wanting even more cuts. A key part of the measure is nearly $800 billion in reduced spending for Medicaid, a program that provides health coverage for low- and middle-income households. Republicans are hoping to include new work requirements for adult Medicaid beneficiaries without children that would take effect starting in 2029. Under the proposed plan, adult Medicaid recipients would need to submit paperwork every month showing they worked at least 80 hours or qualified for an exception. Democrats, and some swing-vote Republicans, have warned that millions of Americans will lose health care coverage if the provision goes into effect.

Indeed, an estimate from the nonpartisan Congressional Budget Office found that the Medicaid changes would reduce the number of people with health care by at least 7.6 million. But proponents say that the new work requirements are estimated to save $300 billion over a decade, while also creating incentives for work.
