The House of Representatives blocks Trump's plan to cut taxes and make social cuts.

Approval of US President Donald Trump's sweeping fiscal and budget plan, which includes tax cuts and spending cuts, stalled Wednesday night due to opposition from some Republican members of Congress.

At least five lawmakers from Trump's party voted, along with the entire Democratic caucus, against bringing the budget to the floor for debate and a vote, and others have yet to cast their votes, so the bill's progress remains, for now, blocked.

The Republican majority in the House over the Democrats is so narrow (220-212) that Trump's party cannot afford to lose more than three votes from their own ranks.

However, House Speaker Mike Johnson, a Republican, has expressed confidence that he will soon be able to convince enough lawmakers in his caucus to move the bill forward.

If the House of Representatives approves the procedural vote, the substantive debate on the bill's content will begin, which could last more than two hours, and then the bill will be put to a final vote.

Trump had no public agenda this Wednesday and spent the entire day holding calls with Johnson and Republican lawmakers to seek House approval for what would be the first budget of his second term, which he has dubbed "the big, beautiful bill."

"It looks like the House is ready to vote tonight. We had excellent conversations all day, and the House Republican majority is united, for the good of our country, achieving the largest tax cuts in history and massive growth," the president declared on the Truth Social network.

Trump, who wants the tax plan passed in time to sign it on Independence Day on Friday, added in another message : "Go Republicans, defeat the corrupt Democrats tonight!"

The processing of the package, which was already approved by the Senate after a marathon vote, has faced several challenges in recent hours.

Severe storms in parts of the country forced a delay in the vote, as several members of Congress were unable to reach Washington on time due to flight and train cancellations and delays.

In addition, a group of hardline Republicans opposes the bill, arguing that it would increase the country's deficit and public debt.

Some lawmakers also fear that the proposed cuts to services like Medicaid will be felt in next year's midterm elections .

The bill includes significant tax cuts, social program cuts, increased spending on defense and border security, and taxes on remittances and renewable energy.

The bill is estimated to increase the federal deficit by more than $3 trillion, given that tax revenue cuts far outweigh public spending cuts. It also raises the government's debt ceiling.

Business magnate Elon Musk, who was a close ally of Trump during his first months in office and the man in charge of devising the bureaucracy cuts, has been one of the most vocal critics of the project.
