This is NBC Nightly News with Lester Holt. Good evening, everyone, and welcome. Severe weather on the march in the east tonight forcing thousands of flight delays and cancelations in Washington, D.C. The government allowed federal workers to go home early today. D.C. under a tornado watch until mid evening. The Storm Prediction Center warning of a widespread damaging wind event this evening.

The line of storms on a track from Mississippi to Maine. Heavy rain, flash flooding and large hail in the forecast. Airports including Baltimore, Newark and Philadelphia experiencing ground stops tonight. All of this being ushered in by a cold front as blistering heat brings continuing trouble across much of the rest of the country. Vaughn Hillyard is in Washington where folks are bracing for a real storm threat from.

That's right, Lester. Folks here in the region have not received a storm warning like this in more than a decade. A storm with potential threats to like impact of lightning and gusty winds that's now descending right here onto the East Coast. Tonight, the summer of severe weather from coast to coast is raging on. Wild weather closing in. Forecast to bring the strongest storms in a decade into the nation's capital, including damaging winds, tornadoes, heavy rain and hail forcing government buildings around Washington, D.C. to shut down, sending all federal employees home this afternoon.

Ground stops at airports across the Eastern Seaboard from Atlanta to D.C. to New York as the FAA reroutes flights to avoid the storm with more than 6000 delays and 1300 cancelations nationwide.

It's very frustrating. Very, very frustrating.

If I wasn't such.

A big girl, I'd actually cry. It comes as 84 million from Tennessee to New York are under the threat of up to 75 mile per hour winds. It looks like a bus is on its side. Heavy rains are also being looked at as a potential cause of a deadly charter bus collision just outside Harrisburg, Pennsylvania, where three people were killed and dozens more were injured, including several children.

It had flipped and everyone just kind of was falling off to the side.

It was was intense.

The same storm system moving east hammered the Midwest over the weekend. A confirmed EF2 tornado with wind speeds as high as 135 miles per hour, reducing several homes in central Illinois to rubble. Now, a massive swath of the country is bracing for more. Bonnie Hilliard, NBC News, Washington.

In Southern California, authorities are investigating why two helicopters fighting a fire collided last night. One of the choppers crashed, killing two fire officials and the pilot. The other chopper was able to land safely with two people on board. The aircraft were involved in efforts to contain a small brush fire in Riverside County. Tonight, lawyers for former President Trump firing back after a request by the special counsel for a protective order concerning evidence in that case involving the 2020 election.

Kelly O'Donnell has late details.

Tonight, a new push in the legal tug of war between former President Trump and the special counsel.

Since free speech. This means that we cannot ever criticize.

In a late filing. Trump lawyers countered Jack Smith's request for a protective order, arguing it violates his First Amendment rights. Worse, it does so against its administration's primary political opponent during an election season. The special counsel asked the court to, in effect, put up guardrails to protect the government's evidence. A consequence of Mr. Trump's prolific social posts among them.

If you go after me, I'm coming after you. The special counsel writes, It could have a harmful, chilling effect on witnesses or adversely affect the fair administration of justice in this case. Mr. Trump firing off his own response. No, I shouldn't have a protective order placed on me because it would impinge upon my right to free speech. Trump Attorney John Lauro Outline Defense Strategy.

Mr. Trump had every right to petition government and enforce his First Amendment rights.

And made headlines when he described Mr. Trump's pressure on Pence to halt the electoral count.

A technique of violation of the Constitution is not a violation of criminal law. That's just plain wrong.

The Trump legal team argues a court order should focus on only the most censored of government documents and not restrict Mr. Trump from talking about all of the evidence. The judge could rule at any time.

Lester kelly o'donnell, thank you. That brings us to our exclusive with Mr. Trump's top rival, Florida Governor Ron DeSantis, who is still trying to make a dent in Mr. Trump's lead. During the interview, Dasha Burns pressing DeSantis about his views on the 2020 election.

Tonight, Florida Governor Ron DeSantis predicting success despite struggling to gain traction against the Republican frontrunner. Trump's lead has only grown since you began campaigning in earnest. Is it possible that you're potentially just out of step with what GOP voters are looking for right now?

So if I had a nickel for every naysayer I've had in my life, I'd be a very, very wealthy man and arguing.

Former President Trump brings distractions that help Democrats.

If the election is a referendum on Joe Biden's policies and the failures that we've seen and we are presenting a positive vision for the future, we will win the presidency. If, on the other hand, the election is not about January 20th, 2025, but January six, 2021, or what document was left by the toilet at Mar a Lago? If it's a referendum on that, we are going to lose.

Can we just put this to bed so you don't have to be asked about this a million more times? Yes or no? Did Donald Trump lose the 2020 election?

Whoever puts their hand on the Bible on January 20th every four years is the winner.

But respectfully, you did not clearly answer that question. And if you can't give a yes or no wonder whether or not Trump lost, then how can worse now? Of course he.

Lost.

Trump loss of 2020. Of course, Joe Biden.

Is the president.

And we pressed Santos on his new border proposal to allow deadly force against drug traffickers demonstrating, quote, hostile intent. You've said if cartels are trying to run product into this country, they're going to end up stone cold dead. How far might you take that method for preventing illegal crossings in general?

No, it's similar to like if you're in the military, you have rules of engagement. Anyone that's hostile intent or a hostile act, which the cartels are, you know, you would then engage with lethal force.

You yourself were an advisor to Navy SEALs. You know how hard it is sometimes when it comes to rules of engagement. How do you discern if it's a child's mother or obviously a child?

I mean, you're not going to do that. But I mean, they.

Have put a pregnant mom in a baseball cap with a backpack.

They have this they have indications. I mean, I think it's I mean, if you have people blow torching through a border wall, that is not going to beat us.

But as you mention, how do you know you're using deadly force against the right?

You would do in any situation, same way a police officer would know, same way somebody operating in Iraq would know. You know these people in Iraq at the time. They all look the same. You didn't know who had a bomb strapped to them. So those guys have to make judgments.

DeSantis often out on the trail with his wife, Casey, a former TV news anchor, touting his record, including on COVID.

I saw him standing up to people in Washington, D.C. We're telling him, you're doing it wrong. You have to shut down the beaches. You have to lock kids out of school. So when you see that firsthand and you understand the fight that he was taking, like, why would I not be in this fight? Why would I not want to be out there singing from the rooftop that this is a good dude.

And their three young kids also along for the ride. Casey describing how her husband supported them when she was diagnosed with breast cancer two years ago.

He was there for me and he was there to go pick up my kids when I couldn't. And he did it with humility. And he did it with love. And I tell you what. Can't ask for a better husband.

Doctor. Joining me now, Dr. DeSantis is making a big campaign stop later this week.

Lester, the iowa state fair kicks off. Both desantis and trump are expected to be there. And the desantis team tells me that trump's lead is softer here than it is in some other states and they can chip away at it.

Lester Garcia Burns, thank you. With tensions soaring in the Persian Gulf, the U.S. has deployed thousands of military personnel and two ships to protect oil tankers. Courtney Kuby is following this and the Pentagon. And Courtney, this is all a response to a growing threat from Iran.

Yeah, that's right, Lester. Those two U.S. warships with more than 3000 U.S. sailors and Marines are now in the Red Sea. Ordered there after Iranian naval vessels tried to stop board and seize two oil tankers near the Strait of Hormuz last month, even firing on one and striking one of those ships. In both cases, the Iranian boats turned away after a U.S. military ship and aircraft arrived.

And that followed an April incident when masked Iranian commandos seized an oil tanker in the Gulf of Oman. Iran's foreign ministry saying the US military presence only fuels instability in the region. Iran has either seized or attempted to seize nearly 20 ships in the past two years. Lester.

All right, Courtney Kuby, thank you. In 60 seconds, disturbing questions after the brawl at a riverfront dock in Montgomery, Alabama. Was race a factor in the fight? What the video show and the growing fallout next. Caught on camera in Texas, a fireball rising from massive explosions at a Sherwin-Williams paint factory outside Dallas. Officials say one employee was injured and treated on the scene overnight.

A hazmat team was deployed to monitor air quality. The cause is under investigation and also captured on video. A violent brawl in Alabama that appeared to involve a group of white boaters attacking a black dockworker. Tonight, police have issued arrest warrants in the case. Here's Priscilla Thompson. Get.

Outrage is growing across the country over these now viral videos appearing to show more than a dozen people in an all out brawl on the downtown Montgomery riverfront. No arrests have been made, the mayor says, but investigators have issued four arrest warrants and say they're reviewing videos of the incident and that more could be coming.

It's something that shouldn't have happened and it's something that we're investigating right now.

The chaos unfolded Saturday night after witnesses say a worker asked a group multiple times to move their pontoon so a commercial riverboat could dock. Krista Owens says she filmed this video from on board the riverboat.

They're mad at this guy who came off our boat is untying his boat and touching it, but it needed to move.

A brawl starts and within seconds. Several people appear to join in.

Witnessing our crewman being attacked by these guys and we couldn't do anything about it. I mean, we don't even.

Get work carried. After the river boat docks. Fighting erupts again. Police on the ground struggling to contain the chaos, but eventually getting some in handcuffs. The mayor now placing the blame on several reckless individuals for attacking a man who was doing his job and vowing that justice will be served. The mayor declined to say whether investigators believe the fight was racially motivated, adding only that the investigation is ongoing.

Lester.

All right, Priscilla, thank you. Up next, new warnings about the dangers of nursing pillows when used the wrong way. Our NBC News investigation into deadly incidents involving the pillows and what experts say parents need to know. And back now with our NBC News investigation into a popular baby product, nursing pillows. Our reporting reveals they've been linked to more infant deaths than the government has announced.

Now the government is planning new safety regulations. Vicki Wynne has what parents need to know.

Taylor Wells returned to work when her daughter Autumn was six weeks old and entrusting her baby to day care staff near her Mississippi home.

She was sweet and she was happy. She laughed all the time.

But in March of 2022, Taylor's phone rang at work.

The first thing I hear is you need to get to the hospital. Autumn's not breathing. So, you know, of course I run as fast as I can. I ran into the emergency room and I said I could tell. I could see them working on her.

Four month old Autumn was found face down on a nursing pillow covered completely with a blanket, according to her death certificate. It showed she died of asphyxiation.

It's hard to even describe what happens when they tell you that your child is no longer with you.

More than a million nursing pillows are sold in the U.S. each year. They're designed to position baby and mom comfortably for breastfeeding. But an NBC News analysis of internal federal documents and public records found more than 160 babies have died in incidents involving nursing pillows since 2007, most commonly when the pillows were used as sleeping devices or to prop babies up.

Babies are dying in the products and they shouldn't be.

Commissioner Rich Trumka with the Consumer Product Safety Commission, says later this month, the agency will propose its first safety regulations for nursing pillows. CPSC has known about infant deaths linked to these nursing pillows for decades. Why hasn't the agency taken action sooner?

So when I got here a year and a half ago, the agency had recognized the hazard and had already commissioned a study.

Researchers found nursing pillows that were firmer with more defined edges were safer. Some of these products have labels with pictures showing different ways to use the nursing pillow that is not related to breastfeeding. Is that okay or not?

I've got great concerns about that.

Labels warn against allowing babies to sleep in the pillows. Are the pillows the problem or is the problem that people aren't using them properly?

You know, we're not going to blame the parents who are using these pillows. If a product is sold to you and it looks like it can be used for sleep, it should be safe for sleep. And we want to make sure that things that aren't for sleep don't look like you can lay your baby down on them.

Boppy and echo, the makers of two popular nursing pillows pointed NBC News to an industry funded group which says drastically changing the shape of the vast majority of nursing pillows could have a negative impact on breastfeeding. The group is funded partly by Boppy Leach Co is a member. Emergency medicine pediatrician Dr. Lois Kay Lee says babies should be placed on their backs on a flat surface to sleep without any soft objects.

My recommendation to parents is.

Absolutely use it to support breastfeeding.

So you're comfortable and the baby's comfortable. But after that, put it away.

In June, Taylor Wells welcomed baby Eliza. She's hopeful any new government rules on nursing pillows will include a broad campaign to reach parents and caregivers everywhere.

That's what we really need. We need education because that is that is what is going to save lives. That's what's going to save babies.

For now, experts say only use nursing pillows while breastfeeding and never leave a baby alone in one. Vicki Winn, NBC News, Belmont, Mississippi.
