WILLIAM BRANGHAM: Welcome to the "News Hour."

Now missing just his signature, President Donald Trump's agenda will have the force of law tomorrow.

The so-called One Big Beautiful Bill overcame thin Republican majorities and weeks of tense negotiations just meeting the president's self-imposed Independence Day deadline.

Congressional correspondent Lisa Desjardins takes us through the policy and politics of the Republican signature bill.

REP. MIKE JOHNSON (R-LA): The yeas are 218, the nays are 214.

The motion is adopted.

LISA DESJARDINS: For the GOP, a victory years in the making.

House Republicans cheered after a long week of overnight and nail-biter votes ended historically, passage of what they named the One Big Beautiful Bill with some $4.5 trillion in tax cuts and $1.4 trillion in spending cuts.

Both are records, as is the $3.2 trillion the Congressional Budget Office says this could add to the deficit.

REP. MIKE JOHNSON: This is the vote tally card.

We're going to frame this one, OK?

LISA DESJARDINS: For House Speaker Mike Johnson, a hard-fought moment to savor.

REP. MIKE JOHNSON: Mr. Speaker with One Big Beautiful Bill, we are going to make this country stronger, safer and more prosperous than ever before.

And every American is going to benefit from that.

LISA DESJARDINS: President Trump was jubilant about his most sweeping legislative accomplishment.

DONALD TRUMP, President of the United States: We're sort of celebrating like the biggest bill of its kind ever signed.

And it's going to make this country into a rocket ship.

LISA DESJARDINS: The president was the closer in chief, pushing and pressuring the bill through, especially when it hit a wall last night.

A House vote was frozen, as Republican opponents refused to let the bill advance.

Trump posted shortly after midnight: "This should be an easy yes-vote.

Ridiculous."

Then he was on the phone with the holdout, who had wanted more conservative social and fiscal policy.

Not long after that, the vast majority flipped.

A day earlier, Texas Republican Chip Roy and others had posted their lists of problems in the bill.

But, today, from those opponents: REP. TIM BURCHETT (R-TN): Don't count out Trump.

Daggum that guy, I wouldn't want to play poker with him.

LISA DESJARDINS: Full embrace of the bill.

A day of go, many of you had major problems.

REP. TIM BURCHETT: Major problems.

And that's why President Trump understood.

LISA DESJARDINS: And yet the bill did not change.

Your vote did.

REP. TIM BURCHETT: Yes, the timing of everything, and Trump understands that.

And I believe that's why they called the vote last night, because that put everybody at the table, and they said, this is the deadline.

REP. GREG MURPHY (R-NC): I spoke with him.

I spoke with the vice president, also, and after listening to them and thinking about it for a while, I went ahead and made the vote.

LISA DESJARDINS: Per multiple holdout members, Trump gave assurances about how he would implement the bill and tighten benefits, stepping up checks for possible undocumented immigrants.

Immigration policy is also in the bill, $150 billion, including for a border wall and mass detention.

It cuts billions in tax credits for wind and solar, and it makes the largest changes ever in the social safety net, Republican reforms of systems they don't trust, some cuts to SNAP benefits, and hundreds of billions cut in future Medicaid spending.

Earlier this year, Trump pledged not to harm those eligible.

DONALD TRUMP: Medicaid, we're not going to do anything with that, other than, if we can find some abuse or waste, we will do something, but the people won't be affected.

It'll only be more effective and better.

LISA DESJARDINS: But the CBO concluded that, overall, nearly 12 million will lose health insurance because of the bill, including millions now on Medicaid.

REP. JAMES CLYBURN (D-SC): If cutting a trillion out of Medicaid is what we call progress, I'd like to see what failure is.

LISA DESJARDINS: This was central to Democratic outcry over the bill, one they see as dangerous to those most vulnerable.

House Democratic Leader Hakeem Jeffries spoke for nearly nine hours on the House floor, further delaying the vote and breaking a record for talk time in the chamber.

REP. HAKEEM JEFFRIES (D-NY): Never in my time here in Congress have I experienced legislation that benefits so few people.

LISA DESJARDINS: But Republicans are betting that their tax cuts spark massive economic growth.

They will celebrate more tomorrow with a July 4 signing ceremony.

Now, this was a messy, tricky process, house leadership and Senate leadership threading multiple needles, overnight votes, reading bills late.

But, in the end, William, one Republican leadership source said, voters don't remember the process, they remember the result.

WILLIAM BRANGHAM: Lisa, this came down to those so-called fiscal hawks, the holdouts.

What else do we know about why they changed their minds?

What kinds of assurances did they get that got them to yes?

LISA DESJARDINS: In the end, I think it really was just Trump pressure.

But they told me a few things, one, that the president indicated to them that he was going to put new tariffs on solar and wind products all along the supply chain.

Now, that's interesting because already there are very heavy tariffs, as we have reported on the show, on that.

But they felt reassured because they were worried that the bill didn't do enough to cut solar and wind.

The president said he's going to do more.

Now, in addition, on undocumented immigrants, that's a limitation that was in the House bill cut from the Senate, the president told them that he plans to step up eligibility requirements or eligibility checks in things like Medicaid to make sure undocumented immigrants are not on the federal plan.

Now, already there's a lot of eligibility checks, so we have to watch what that means.

WILLIAM BRANGHAM: So what does each party see about what happens next?

LISA DESJARDINS: Right.

This is fascinating because this bill really could drive the next political cycle entirely on its own.

Republicans are going to start messaging that they believe the economy is being unleashed here, that this will be good for business, this will be good for individuals.

They will be talking a lot about this.

Now, Democrats, on the other hand, aren't worried about that message because they believe the effects of this bill, people will feel them in their own lives.

People will be losing health care.

They may be having more struggles, especially at those kinds of things.

So Democrats think, in the end, because they see this bill as dangerous, that it will benefit them.

Both parties acknowledge that this will be something probably that will affect them on the ballot in 2026.

WILLIAM BRANGHAM: And what do we know about the effects of this bill and when those might be felt by voters?

LISA DESJARDINS: Right.

The biggest effect is one that actually no one will feel.

The tax cuts in this bill largely mean that tax rates don't change at all.

That's the most expensive part of this.

So it's staving off a tax increase, but that is something that people should be aware of.

Now, otherwise, there are some cuts already being felt like Medicaid cuts, even though technically they don't go into place until 2027, 2028.

Today, there was a community hospital in Nebraska in the last 24 hours that came out and said this.

This is community hospital in Curtis, Nebraska, writing that they feel that now because of anticipated Medicaid cuts and other financial problems they have had that they're going to close that clinic in Curtis.

I spoke to officials in that town, this very small town.

They said to me they only have a physical therapist in that town.

The next closest medical facility is 40 to 50 minutes away.

And they have a small college there as well.

So they're concerned about this.

One other thing I want to talk about that we could see immediate effects from is the immigration money in this bill.

We're talking about tens of billions of dollars for enforcement, detention, deportation.

That's money that will go out almost immediately.

And we know that the Trump administration wants to use it.

WILLIAM BRANGHAM: Lisa Desjardins, you have done such incredible work all week long for us, helping us stay up to speed.

Thank you so much.

LISA DESJARDINS: You're welcome.
