With Independence Day fast approaching, President Donald J. Trump and the White House are turning up the pressure on Republicans in Congress to deliver his signature legislative package — the One Big Beautiful Bill Act — calling it a defining moment for the GOP majority and the American people.

“The One Big Beautiful Bill Act reflects the shared priorities of both the Congress and the Administration,” the White House said in a statement Saturday, calling on lawmakers to fulfill their promises to voters and send the bill to President Trump’s desk before July 4. “President Trump is committed to keeping his promises, and failure to pass this bill would be the ultimate betrayal,” it added, according to the Washington Times.

The legislation, now spanning 940 pages, is the product of weeks of revisions led by Senate Republicans and shaped by direct negotiations between lawmakers and President Trump’s economic team. The House passed its version of the bill last month, and now the Senate is racing to meet Trump’s deadline, holding a procedural test vote over the weekend to begin formal debate.

A cornerstone of Trump’s second-term America First agenda, the bill includes sweeping reforms aimed at unleashing American energy, restoring border security, modernizing infrastructure, and cleaning up the bloated and broken federal budget process.

“This bill implements critical aspects of President Trump’s budgetary agenda by delivering bigger paychecks for Americans, driving massive economic growth, unleashing American energy, strengthening border security and national defense, modernizing America’s air traffic control system, preserving key safety net programs for Americans who need them, while ending waste, fraud, and abuse in Federal spending, and much more,” the administration said.

But while conservatives are working to secure final passage, resistance is coming not only from Democrats — but from inside the machinery of the Senate itself.

Enter Senate Parliamentarian Elizabeth MacDonough — a little-known, unelected bureaucrat who was appointed to her role in 2012 by then-Senate Majority Leader Harry Reid. According to The Daily Caller, MacDonough has taken it upon herself to issue rulings that could strip out key components of Trump’s legislative vision.

Last week, she advised Republicans that several provisions — including efforts to repeal a Biden-era electric vehicle mandate and eliminate a Warren-backed financial regulatory agency — must be removed in order to comply with the arcane rules of budget reconciliation.

Those rulings immediately cast a shadow over some of the bill’s most impactful reforms.

Senate Republicans are utilizing reconciliation to bypass the 60-vote threshold and pass the bill with a simple majority — a strategy Democrats used repeatedly during their years of unchecked control. But now that Trump is back in the White House and Republicans control Congress, the old rules are suddenly being enforced with laser precision.

Anything ruled ineligible under reconciliation rules will need 60 votes to pass — handing Senate Democrats, led by Chuck Schumer, a veto over Trump’s most transformative policies.

Democrats are predictably doing everything they can to obstruct Trump’s agenda. They’ve challenged dozens of provisions in the bill, claiming they don’t meet technical criteria for budget impact. MacDonough, in turn, has already ruled in their favor on several points — effectively shielding Biden-era policies and slashing at the heart of the America First platform.

Despite the hurdles, momentum remains strong.

On Thursday, President Trump held a high-energy event at the White House to rally support for the bill, calling on Senate Republicans to hold the line. That same day, Senate Majority Leader John Thune (R-S.D.) and House Speaker Mike Johnson (R-La.) met with Trump in the Oval Office to chart the final strategy.

“We can get it done,” Trump wrote on Truth Social. “It will be a wonderful Celebration for our Country, which is right now, ‘The Hottest Country anywhere in the World’ — And to think, just last year, we were a laughingstock.”

As the Senate moves into final debate, the outcome will define not only the success of Trump’s legislative agenda, but the willingness of the Republican Party to stand united under pressure.

The White House has made it clear: anything short of delivering this bill to President Trump by July 4 would be a failure — not of politics, but of principle.
