Senator Lindsey Graham suggested Zelensky should resign, adding that Friday’s altercation had imperilled future US military support for Kyiv.

The extraordinary row culminated in Zelensky being asked to leave the White House without signing a deal with the US that would have jointly developed Ukraine’s valuable minerals.

On Saturday, Zelensky enjoyed a much warmer reception from UK Prime Minister Keir Starmer in Downing Street, a day ahead of a meeting with King Charles.

The Ukrainian leader also made a plea on Saturday to the US to “stand more firmly” with Kyiv, adding that he was ready to sign the minerals deal with Trump, but wished for defined security guarantees.

Trump has suggested that Ukraine should concede territory to Russia to end its invasion and has opened peace talks between the US and Russia, which do not include representatives from Ukraine.

The American president has also warned Moscow that he will impose high tariffs and further sanctions if President Vladimir Putin fails to end the “ridiculous” war.

Before leaving for Florida after Friday’s Oval Office clash, Trump told reporters that Zelensky had “overplayed his hand”.

“Either we’re going to end it or let him fight it out, and if he fights it out, it’s not going to be pretty,” Trump said. “Because without us, he doesn’t win.”

Republicans in Washington loyally backed Trump as Democrats said they were horrified by the Oval office showdown before world media.

“What I saw in the Oval Office was disrespectful, and I don’t know if we can ever do business with Zelensky again,” said Senator Graham, a longtime advocate for Ukraine aid and a foreign policy hawk, as he left the White House on Friday.

“The question for me is, ‘is he redeemable in the eyes of Americans?’ Most Americans witnessing what they saw today would not want Zelensky to be their business partner, including me, and I’ve been to Ukraine nine times since the war started.”

Alabama Senator Tommy Tuberville posted on X on Saturday: “The best thing President Trump has done so far is kick that Ukrainian weasel out of the WH.”

Tennessee Senator Bill Hagerty posted on X: “The United States of America will no longer be taken for granted.”

Mike Lawler of New York called the meeting “a missed opportunity for both the United States and Ukraine”.

Don Bacon of Nebraska said Friday was “a bad day for America’s foreign policy”.

“Ukraine wants independence, free markets and rule of law. It wants to be part of the West. Russia hates us and our Western values. We should be clear that we stand for freedom,” he said in a statement.

Neither Republican directly criticised Trump or Vice-President JD Vance, who first quarrelled with Zelensky during the meeting.

Democrats lambasted the White House for the spat with a US ally.

“Trump and Vance are doing Putin’s dirty work,” Senate Minority Leader Chuck Schumer said.

Senator Chris Coons said Zelensky deserved better.

“We owe him our thanks for leading a nation fighting on the front lines of democracy – not the public berating he received at the White House,” he posted on X.

The 217-215 vote was seen as a key early test for Republican House speaker Mike Johnson, who cancelled an earlier vote as it appeared he did not have enough support.

Several Republicans wanted more fiscal discipline from a budget that includes $4.5 trillion in tax cuts, funded partially by spending cuts but also by potentially increasing the US government’s substantial debt pile.

But the bill eventually passed along party lines, with all Democrats voting against and just one Republican opposing it.

That Republican was Thomas Massie of Kentucky, a prominent fiscal hawk who wanted deeper spending cuts. One Democrat did not vote.

The House budget seeks $2 trillion in spending cuts over the next 10 years to pay for President Trump’s agenda. It includes more than $100bn in new spending on immigration enforcement and the military.

It would also extend tax breaks passed during his first term in office, which are due to expire at the end of the year.

However there are still a number of steps the spending plan must go through in order to become law.

The budget will have to be merged with a separate budget which is under consideration by the US Senate, in a process called reconciliation.

And even if both chambers ultimately agree on a spending plan, many finer details will need to be negotiated before it can be sent to President Trump’s desk to be signed.

House Republican leaders initially delayed Tuesday’s vote when it was unclear whether they would have enough support to pass the measure.

Speaker Johnson and the second most senior House Republican, Steve Scalise, spent hours working to convince wavering party members to back the plan which, as well as tax cuts, would fund border security measures, deportations and military spending.

Trump personally called some of the holdouts to encourage them to pass the bill, the two Republican leaders said.

“Trump helped us with a number of members,” Scalise told reporters. “Talking to anybody that we asked that really needed to clarify things.”

Three of the four party holdouts who had been initially seen as firm no votes – Representatives Tim Burchett, Victoria Spartz and Warren Davidson – ultimately voted in favour.

“We have a lot of hard work ahead of us, but we are going to deliver the American First agenda,” House Speaker Mike Johnson told reporters after the vote.

“We’re going to celebrate tonight, and we’ll roll up our sleeves and get right back in the morning.”

Democrats lined up to criticise the budget as a tax cut mostly for the wealthy, which they said would hurt low-income families who rely on the government-funded health care programme Medicaid.

The party worked to get as many members in the chamber for the crucial vote, with Representative Brittany Petterson arriving with her son while on maternity leave.

The Senate will be under pressure to take up the House’s spending framework because President Trump has endorsed it, despite their separate bill which was introduced last week.
