Washington, Feb 25 (AP) House Speaker Mike Johnson will try against the odds to muscle a Republican budget blueprint to passage this week, a step toward delivering President Donald Trump's “big, beautiful bill” with USD 4.5 trillion in tax breaks and USD 2 trillion in spending cuts over stiff opposition from Democrats — and even some Republicans.

With almost no votes to spare in Johnson's bare-bones GOP majority, the speaker is fighting on all fronts — against Democrats, uneasy rank-and-file Republicans and sceptical GOP senators — as he works to keep the package on track. Votes set for Tuesday evening are in jeopardy, and the outcome is uncertain.

“We're going to get everyone there,” Johnson, of Louisiana, said at an event at the start of the week, half-joking that he had a “prayer request” involved.

The package, if approved, would be a crucial part of the budget process as Trump pushes the Republicans who control Congress to approve a massive bill that would extend tax breaks, which he secured during his first term but are expiring later this year, while also cutting spending across federal programmes and services.

Slashing government is not always popular at home But Republicans are running into a familiar problem: Slashing federal spending is typically easier said than done. With cuts to the Pentagon and other programmes largely off limits, much of the other government outlays go for health care, food stamps, student loans and programmes relied on by their constituents.

It's all unfolding as billionaire Trump adviser Elon Musk is tearing through federal agencies with his Department of Government Efficiency firing thousands of workers nationwide, and angry voters are starting to confront lawmakers at town hall meetings back home.

“While we fully support efforts to rein in wasteful spending and deliver on President Trump's agenda, it is imperative that we do not slash programmes that support American communities across our nation,” wrote Rep. Tony Gonzales, R-Texas, and several other GOP lawmakers in the Congressional Hispanic Conference.

Democrats protest tax cuts for wealthy Democrats in the House and the Senate are vowing to fight the whole process. House Democratic Leader Hakeem Jeffries of New York was planning to gather lawmakers on the Capitol steps in protest during Tuesday's session.

“This is not what people want,” said Rep. Jim McGovern, D-Mass., during a rules debate ahead of planned votes.

“We all know that trickle-down economics,” he said about the 2017 tax breaks that flowed mainly to the wealthy, “don't work.” Trump has signalled a preference for the “big” bill but also appears to enjoy a competition between the House and the Senate, lawmakers said, as he pits the Republicans against each other to see which version will emerge on a path toward approval.

Senate Republicans, wary that Johnson can lift his bill over the finish line, launched their own scaled-back USD 340 billion package last week. It's focused on sending Trump money his administration needs for its deportation and border security agenda now, with plans to tackle the tax cuts separately later this year.

“I'm holding my breath. I'm crossing my fingers," said Sen. John Cornyn, R-Texas, who said he is rooting for the House's approach as the better option. "I think a one-shot is their best opportunity.” The House GOP faces pitfalls ahead Johnson, whose party lost seats in last November's election, commands one of the thinnest majorities in modern history, which means he must keep almost every Republican in line or risk losing the vote.

Already, several lawmakers have objected to the package either because it cuts too much or because it doesn't cut enough.

The most conservative Republicans warn it will pile onto the nation's USD 36 trillion debt load, because the cost of the tax breaks, at least USD 4.5 trillion over the decade, outweighs the USD 2 trillion in spending cuts to government programmes.

More moderate Republican lawmakers worry that the enormous budget cuts being eyed — some USD 880 billion to the committee that handles health care spending, including Medicaid, for example, or USD 230 billion to the agriculture committee that funds food stamps — will be too harmful to their constituents back home.

GOP leaders are trying to convince lawmakers that the details will be debated in the weeks to come and that this week's vote is just a first step.

The budget is being compiled during a lengthy process that first sends instructions to the various House and Senate committees, which will then have several weeks to devise more detailed plans for additional debate and votes.

“The committees need time to go work to find savings," said Majority Leader Steve Scalise, R-La. "But we can't even get to that if we don't get through the budget. So, we've got to get the first step done later this week.” Ten House GOP chairmen of the committees involved issued a joint statement in a show of force to push the package forward.

“The House's one big beautiful bill' delivers on the entirety of President Trump's policy agenda,” they wrote in a letter obtained by The Associated Press. “We must meet this historic moment with the bold action it requires.” Rep. Jodey Arrington, the Republican chairman of the House Budget Committee, told reporters he recognises the tension between Republicans who want more cuts and those from politically competitive districts who “have a higher level of sensitivity to some of the spending reforms." Arrington said with economic growth assumptions, from 1.8 per cent as projected by the nonpartisan Congressional Budget Office to 2.6 per cent as projected by House Republicans, the package would generate about USD 2.6 trillion in savings over 10 years and would ensure the plan helps reduce the deficit.

Budget blueprint faces jeopardized votes as intra-party opposition and rival Senate proposals threaten its procedural passage. House Republican leadership is advancing a unified budget blueprint combining tax extensions and spending reductions, using an initial House floor vote as a procedural step to send instructions to committees for detailed implementing legislation. The proposal relies on contested economic assumptions to project savings, has provoked intra-party opposition over projected program cuts, and faces additional complication from an alternative Senate proposal focused on narrower funding priorities, leaving passage uncertain.
