Republican-led House passes Trump agenda bill by a single vote

After weeks of internal GOP wrangling, the Republican-led House early Thursday passed the "One Big Beautiful Bill Act," critical to advancing President Donald Trump's tax and immigration agenda.

A smiling Speaker Mike Johnson announced the massive measure passed by a single vote -- 215-214 -- and was greeted with applause. He had struggled to get it done -- as he had promised -- by Memorial Day, before lawmakers go on recess.

The sweeping package of tax cuts, Medicaid reform and immigration spending delivers on many of the president's domestic campaign promises.

Following debate that stretched Wednesday through the entire night and into early Thursday morning, the vote was a triumphant moment for Johnson, who conquered sharp divisions among his conference "through a lot of prayer" amid a historically low 3-vote majority.

"The bill gets Americans back to winning again, and it's been a long time coming," Johnson proclaimed during his speech on the floor moments before the final vote. "It quite literally is again morning in America, isn't it, all right?"

Trump celebrated the passage of what he called "THE ONE, BIG, BEAUTIFUL BILL" in a social media post, calling it the "most significant piece of Legislation that will ever be signed in the History of our Country!"

He said it fulfilled his campaign promise of "No Tax on Tips and No Tax on Overtime." He also recognized the tax deductions when consumers purchase an American-made vehicle, funding for the Golden Dome defense system, and the "TRUMP Savings Accounts" incorporated in the legislation.

"Great job by Speaker Mike Johnson, and the House Leadership, and thank you to every Republican who voted YES on this Historic Bill!," Trump wrote.

"Now, it’s time for our friends in the United States Senate to get to work, and send this Bill to my desk AS SOON AS POSSIBLE!" Trump added, before slamming Democrats.

During the final House vote, Republican lawmakers approached the speaker with congratulatory handshakes and back slaps. Someone also played Queen's "We Are The Champions" off a phone for about 10 seconds while the vote was underway.

Republicans cheered, whistled and applauded when the threshold for passage was achieved at 6:54 a.m.

The successful vote, with one GOP lawmaker voting present, sends the reconciliation bill to the Senate, where the Republican majority is expected to revise the legislation over the next month or longe

Two House Republicans, Reps. Thomas Massie of Kentucky and Warren Davidson of Ohio, opposed the vote alongside the entire House Democratic Caucus. Rep. Andy Harris, the chairman of the House Freedom Caucus, voted present.

Johnson took a victory lap following the vote – holding a news conference alongside his leadership team and committee chairs – after Republicans pulled off the improbable and passed the president's signature legislative package.

"It's finally Morning in America again," Johnson beamed as he repeated his earlier comment. "The media and the Democrats have consistently dismissed any possibility that House Republicans could get this stuff. They did not believe that we could succeed in our mission to enact President Trump's America first agenda, but this is a big one, and once again, they have been proven wrong."

After a marathon hearing that ended overnight, the House Rules committee voted 8-4 to tee up action on the House floor.

The committee vote came after changes to several of the bill's provisions, including a change to when Medicaid work requirements would kick in.

Texas Republican Rep. Chip Roy, one of the GOP holdouts that had put the bill's fate in question, was absent for the committee's votes.

The key procedural step was needed before advancing the legislation to a final vote.

The slow march toward passage comes after Trump met with House Speaker Mike Johnson and members of the House Freedom Caucus on Wednesday, aiming to shore up support for the bill.

That meeting came after earlier negotiations with hard-liners fell apart Tuesday. The GOP is far from unified around the bill, which they earlier had said they hoped to move to a vote on Wednesday. Several sticking points, primarily regarding Medicaid work requirements and a cap on state and local tax deductions, still need to be worked out.

After the meeting, White House press secretary Karoline Leavitt said, "The meeting was productive and moved the ball in the right direction. The President reiterated how critical it is for the country to pass the One Big Beautiful Bill as quickly as possible."

Clearing the House is just the first hurdle for the bill -- it will also have to pass muster with a Senate Republican conference that is already telegraphing that they plan to make changes.

Here are the major changes to the bill in the 42-page amendment:

Medicaid: The start date for new Medicaid work requirements will now kick in "no later than December 31, 2026." The original bill had the work requirements starting in 2029.

This alteration is a win for hardliners who have for days been pushing for steeper spending cuts to be included in the package. Medicaid work requirements are expected to reduce spending in the bill.

There is also a new incentive for states to not expand Medicaid. Medicaid expansion states are increasing state-directed payments up to 110% to maintain the structure.

State and Local Tax Deductions: SALT deduction rises to $40,000 for incomes under $500,000. This is a substantive change from the $10,000 cap that was implemented by Republicans in the 2017 Tax Cuts and Jobs Act.

This is a concession geared toward satiating blue-state Republicans in states like New York and California. Many of them conditioned their support for the package on lifting or raising the cap on these deductions. Moderates will brand this as a big win.

Maga Savings Account: The amendment changes the names of these accounts. Instead of MAGA Accounts, they will now be called "Trump" Accounts. The president's last name appears in the manager's amendment +50 times.

Expedited cuts to clean energy credits: Some of Biden-era clean energy tax credits will phase out sooner, allowing Republicans to recoup costs to apply toward the overall cost of the bill. To receive credits, new projects must break ground within 60 days or be "placed in service" by the end of 2028.

Billions in border security reimbursements: The Department of Homeland Security appropriates $12 billion to states for costs associated with Biden-era border actions through September 30, 2029. The DHS Secretary can authorize grants to assist with immigration enforcement.

Ends tax on silencers: The manager's amendment delists silencers from the National Firearms Act, effectively ending a tax on transferring silencers.
