(WASHINGTON) -- The "One Big Beautiful Bill Act" -- a massive tax and immigration bill to fund much of President Donald Trump's agenda -- could add $2.4 trillion to the deficit over the next decade, according to a new analysis out Wednesday from the nonpartisan Congressional Budget Office.
The CBO released updated estimates on the legislation as focus turns to the Senate, where a handful of Republican members are expressing concerns about the deficit and changes to Medicaid.
The budget office is projecting 10.9 million more people will be uninsured in 2034 because of changes to health care.
The budget office also estimates the bill will cut taxes by $3.7 trillion and cut spending by $1.2 trillion. The CBO has not yet completed an analysis of the macroeconomic effects of the bill.
The White House preemptively defended the bill just before the CBO release, with deputy chief of staff Stephen Miller accusing the nonpartisan office of being "lefty" and touting the legislation as a "dream bill."
House Majority Leader Steve Scalise slammed the CBO report at a press conference with Republican leadership on Wednesday morning, taking issue with it not recognizing potential economic growth, which it will do in a later, separate estimate.
"I get that we got to play by the rules of the referee, but the referee's been wrong. We've got a referee that tries to sack our quarterback a lot," Scalise said.
The bill narrowly passed the House in May, but now some GOP members are signaling regret on their stamp of approval. Georgia Rep. Marjorie Taylor Greene, a staunch Trump ally, wrote in a social media post that she wasn't aware of a provision related to AI regulations and that she would have voted against the bill had she known it was included. Greene called for the measure to be removed by the Senate.
Later Wednesday, President Trump will meet with Senate Finance Committee at the White House in his push to have the megabill passed by July 4.
The president's lashed out at GOP senators who are threatening to complicate its path forward, including Kentucky Sen. Rand Paul. Paul, who is specifically taking issue with the deficit, told ABC News following Trump's attacks that he's been "consistent" about his view from the start.
Sen. Ron Johnson, a Wisconsin Republican who sits on the Senate Finance Committee, has been critical of the bill the House passed to the Senate because it adds to the deficit.
"I refuse to accept $2 trillion-plus deficits as far as the eye can see as the new normal. We have to address that problem, and unfortunately this bill doesn't do so," Johnson said during an appearance on ABC News Live on Wednesday following the CBO release. The senator said regardless of individual CBO scores, the trajectory of deficits and debt is "hard to dispute."
Senate Minority Leader Chuck Schumer, the chamber's top Democrat, pointed to the CBO analysis as he railed against the Trump megabill in a press conference on Wednesday.
"The more you look at the bill, the worse it gets," Schumer said. He slammed the impact the changes to Medicaid are projected to have on people's health insurance as well as on rural hospitals and nursing homes.
"People will fall through the cracks and get phased out of coverage in the coming years. Death by 1,000 paper cuts. That's the intention of the Republican bill," he said.
