WASHINGTON — The Trump administration prodded Republicans in Congress to “get to work” Monday on the president’s marquee tax and border security legislation — with House Speaker Mike Johnson (R-La.) visiting the executive mansion to get his marching orders for the critical coming months while Treasury Secretary Scott Bessent met on Capitol Hill with Senate Majority Leader John Thune (R-SD).

“The president has made his priorities clear. The House is moving things along quickly and the Senate is in lockstep,” Bessent told reporters after emerging from the closed-door meeting.

“We think that they are in substantial agreement — and that this is gonna be a win for the American people, very pro-growth,” he added.

“We’ve got three legs to the president’s economic agenda — trade, tax, and deregulation — and we hope that we can have this tax portion done by Fourth of July.”

Johnson was also bullish when speaking with reporters after coming back up Pennsylvania Avenue from his sitdown with Trump.

“I just had a great meeting with the president at the White House,” the speaker announced, “he’s in good spirits and we are as well.”

House and Senate Republicans crafted the budgetary framework earlier this month, including an increase to the nation’s debt limit of up to $5 trillion, an extension of Trump’s 2017 Tax Cuts and Jobs Act costing at least $4.5 trillion and as much as $350 billion in new border funding.

James Blair, the White House’s deputy chief of staff for legislative affairs, pointed to Republicans’ stated goal of “eliminating waste, fraud and abuse,” which got a jumpstart under the Elon Musk-led Department of Government Efficiency (DOGE).

The Senate’s reconciliation bill framework initially called for only a few billion dollars in mandated spending cuts, but GOP aides have claimed other proposed reductions — including the elimination of billions of dollars’ worth of energy provisions in the Biden-era Inflation Reduction Act — are expected to be worth a much greater amount.

“We think there’s a path to deliver the requisite spending reforms,” Blair told reporters alongside Bessent and White House National Economic Council Director Kevin Hassett.

When asked by reporters how Trump could guarantee that inflation won’t spike due to the package, Bessent answered: “What we can guarantee is that for working-class Americans, that if this doesn’t pass we’ll have the largest tax hike in history — and that when it does, they will see substantial savings.”

The Treasury secretary said during his January confirmation hearing that the “crushing” tax increase caused by letting the president’s 2017 tax law expire would fall squarely “on American manufacturers, service workers and seniors.”

Trump’s other campaign pledges to place no taxes on tips, Social Security, or overtime pay will also make it through Congress, Bessent affirmed, along with “deductibility for auto loans for American-made cars” and “100% expensing for equipment” as well as “factory structures” to reshore industries in the US.

The reconciliation bill will also boost defense spending by between $100 billion and $150 billion, while House Republican fiscal hawks have demanded that the bill include at least $1.5 trillion in federal spending cuts.

Bessent also noted that the “X date” for the nation defaulting on its debt had yet to be reached, with the next deadline to raise America’s credit limit expected sometime in June.

“We are still taking in revenues. I can tell you that revenues are up from last year,” he said. “The US will never miss the X date.”

The Treasury chief also suggested additional revenue from Trump’s global duties will help balance the budget — while maintaining that the baseline 10% duties wouldn’t be reduced without one-for-one deals with America’s trading partners.

“If they don’t want to lower their tariffs, if they don’t want to lower their [non-tariff trade] barriers, if they don’t want to stop manipulating the currencies,” he replied, “then our tariffs will be higher.”

Meanwhile, Republicans from blue states are still discussing how high the state and local tax deduction (SALT) cap will be set, with Rep. Jeff Van Drew (R-NJ) previously telling The Post he’s seeking a $30,000 deduction limit as a starting point.

The 2022 Inflation Reduction Act was the last reconciliation bill to move through Congress and was projected to hike the deficit by $1 trillion over the next 10 years.

Some GOP committees in recent days have put out their own spending levels for the bill, which will be able to pass both chambers of Congress by a simple majority via a process known as budget reconciliation.

That allows the Senate to break the traditional 60-vote filibuster so long as there are no policy changes — only shifts in revenue, spending and the debt ceiling.

“We want Congress to get to work,” White House press secretary Karoline Leavitt told pro-Trump “new media” members earlier Monday as Johnson huddled with Trump to hash out the legislative package.

“Americans making less than $400,000 a year would see a $2.6 trillion tax hike. And a typical family of four making $80,000 would be sending an additional $1,700 to Uncle Sam,” Thune said of the package in a Monday floor speech. “Republicans, Mr. President, do not intend to let that happen.” 

“And our final bill will not only extend the 2017 tax relief for hardworking Americans, it will make it permanent,” he added.

On Sunday, the House Homeland Security Committee kicked things off by releasing its wish list of $46.5 billion for border wall construction, $4.1 billion to hire 3,000 Border Patrol agents and other enforcement employees as well as billions more in tech and special operations funding to crack down on illegal migrant entries and fentanyl flowing into the US from Mexico.
