US Senate begins voting on Trump's 'big beautiful bill'

The US Senate has begun a marathon vote on a sprawling budget that is critical to President Donald Trump's agenda, but the spending plan is hanging in the balance after weeks of fraught negotiations.

Republicans - who control both chambers of Congress - are divided over how much to cut welfare programmes in order to extend tax breaks in the One Big Beautiful Bill Act.

The president's party is sprinting to pass the legislation by this week's self-imposed deadline of the Fourth of July public holiday.

If the measure does clear the Senate, it will have to go back for another vote to the House of Representatives, which passed its own version of the bill last month by a single vote.

Senators zipped through the halls of the Capitol on Monday, making their way to the chamber floor for various amendment votes, then back to their private meeting rooms where they hashed out grievances outside the view of reporters.

Senators are currently arguing for or against adding amendments to the nearly 1,000-page bill in a process called "vote-a-rama", which could entail up to 20 hours of debate.

"We're still obviously perfecting a few things," Senate Majority Leader John Thune said on Monday.

An amendment to the proposal for Medicaid cuts recently proposed by Florida Senator Rick Scott could cause roughly 20 million Americans to lose their health insurance coverage, according to one estimate.

When asked about the report, Thune said there are "lots of analyses out there".

"The thing that [Scott's] bill doesn't do is it doesn't take effect until 2031. So I'm not sure how you can make the argument that it's going to kick any people off of health insurance tomorrow," Thune said.

Democrats, who have repeatedly denounced the bill, particularly for cutting health insurance coverage for millions of poorer Americans, are expected to use all 10 of their allotted hours of debate, while Republicans probably won't.

Senator Adam Schiff, a California Democrat and longstanding critic of Trump, called the bill "terrible".

He told the BBC he was unsure if Senate Republicans would meet Trump's deadline of passage by this Friday, when America celebrates Independence Day, adding that, even if they did, "who knows what happens in the House".

Speaking at the White House on Monday, press secretary Karoline Leavitt said that Trump is "confident" the bill would be passed and still expects it on his desk by his self-imposed deadline.

Senator John Fetterman, a Pennsylvania Democrat, appeared frustrated on Monday afternoon, after no signs of a final draft of the bill emerged.

"Oh my God, I just want to go home," he said, adding that the extended negotiations and voting rounds have caused him to miss his "entire trip to the beach".

"I don't think it's really helpful to put people here till some ungodly hour," he said.

On Sunday, Democrats used a political manoeuvre to stall the bill's progress, calling on Senate clerks to read all 940 pages of the bill aloud, a process that took 16 hours.

The move followed weeks of public discussion and the Senate narrowly moving on the budget bill in a 51-49 vote over the weekend.

Two Republicans sided with Democrats in voting against opening debate, arguing for further changes to the legislation.

One of those Republicans, North Carolina Senator Thom Tillis, announced his retirement following that vote and said the legislation broke promises that Trump and Republicans made to voters.

"Too many elected officials are motivated by pure raw politics who really don't give a damn about the people they promised to represent on the campaign trail," Tillis wrote in his announcement.

The White House reacted angrily to Tillis' comments on Monday, with Leavitt telling reporters the senator is "just wrong" and that "the President and the vast majority of Republicans who are supportive of this legislation are right".

The other Republican who voted against moving the bill was Senator Rand Paul of Kentucky. He objected to the debt increase, and cuts to Medicaid, a healthcare programme that is relied on by millions of elderly, disabled and low-income Americans.

On Monday, Senator Dan Sullivan, an Alaska Republican, sought to quell concerns about cuts to Medicaid, saying "we're going to be fine in this".

When the bill comes up for a full Senate vote - expected either late on Monday night or early Tuesday morning - Republicans can only afford three defections in order for the bill to pass.

If they lose three votes, Vice-President JD Vance will have to cast a tie-breaking vote.

The bill would then return to the House of Representatives, where leadership has advised a full vote on the Senate's bill could come as early as Wednesday morning.

While Republicans control the House, they can also only lose a handful of votes. There are frustrations with the Senate version of the bill among some Republicans in the House, which could make for another close vote.

The fiscal hawks of the Republican-led House Freedom Caucus have threatened to torpedo the Senate version over budget disagreements.

The Senate proposal adds over $650bn to the national deficit, the group said in a post on social media on Monday.

"That's not fiscal responsibility," they said. "It's not what we agreed to."

Democrats in both chambers have largely objected to the spending cuts and the proposed extension of tax breaks.

Meanwhile, Republican debate has focused on how much to cut welfare programmes in order to extend $3.8tn (£2.8tn) in Trump tax breaks.

The proposed cuts could strip nearly 12 million Americans of their health insurance coverage and add $3.3tn (£2.4tn) in debt, according to the Congressional Budget Office, a non-partisan federal agency.

The version of the bill senators will soon vote on contains tax cuts that Trump campaigned on, such as a tax deduction on Social Security benefits, and the elimination of taxes on overtime work and tips.

The bill also authorises $5tn in new borrowing that will add to a swelling US debt load - a move that goes against what many conservatives have argued for and infuriated one-time Trump confidant Elon Musk.

Musk fired off social media posts on Monday attacking the bill, upping the pressure on the president's party as they try to wrestle the bill over the finish line.

"Every member of Congress who campaigned on reducing government spending and then immediately voted for the biggest debt increase in history should hang their head in shame!" the mega-donor wrote on X.

"And they will lose their primary next year if it is the last thing I do on this Earth."

The national debt currently sits at $36 trillion, according to the treasury department.

Treasury Secretary Scott Bessent has urged Congress to address the debt limit by mid-July and warned if they do not, the US could be unable to pay its bills as early as August.
