WASHINGTON — With President Donald Trump’s multitrillion-dollar tax- breaks package at risk of stalling, House Speaker Mike Johnson and conservative Republican holdouts are heading Wednesday to the White House for the last-ditch talks to salvage the “big, beautiful bill.”

Johnson, R-La., had hoped to vote as soon as Wednesday on the 1,000-plus-page bill after grinding through an all-night committee hearing, a final step in the process. But debate dragged into midday. Democrats, without the votes to stop it, are using all available tools to press their opposition and capitalize on the GOP disarray.

“We believe it’s one big, ugly bill that’s going to hurt the American people,” said House Democratic leader Hakeem Jeffries of New York as he and his team testified before the committee.

“Hurt children, hurt families, hurt veterans, hurt seniors, cut health care, cut nutritional assistance, explode the debt,” he said.

Trump had told the Republican majority to quit arguing and get it done, putting his own political influence on the line. But the Republican president failed to move many skeptics during his Capitol Hill visit this week and GOP leaders struggled through the night to craft last-minute deals.

But for every faction of the slim House majority that Johnson appeases, he loses others. A tentative deal with GOP lawmakers from New York and other high-tax states to boost deductions for local taxes to $40,000 alarmed the most conservative Republicans, worried it would add to the nation’s $36 trillion debt.

A fresh analysis from the Congressional Budget Office said the tax provisions would increase federal deficits by $3.8 trillion over the decade, while the changes to Medicaid, food stamps and other services would tally $1 trillion in reduced spending. The lowest-income households in the U.S. would see their resources drop, while the highest ones would see a boost, the CBO said.

Republicans convened the House Rules Committee hearing shortly after midnight Tuesday, but Johnson’s Memorial Day deadline for House passage was slipping as lawmakers prepared to depart for the holiday.

At its core, the package extends tax breaks approved during Trump’s first term in 2017, while adding new ones he campaigned on in 2024.

To make up for some of the lost revenue, the Republicans are focused on spending cuts to federal safety net programs and a massive rollback of green energy tax breaks from the Biden-era Inflation Reduction Act.

Additionally, the package tacks on $350 billion in new spending, with about $150 billion going to the Pentagon and the rest for Trump’s mass deportation and border security agenda.

The CBO has estimated 8.6 million fewer people would have health insurance with the various changes to Medicaid and the Affordable Care Act. It also said 3 million fewer people each month would have SNAP benefits.
