AMNA NAWAZ: In the day's other headlines: President Trump will fire several members of his National Security Council, according to people familiar.

The firings involve at least three unnamed senior NSC officials and several other lower-ranking aides.

National Security Adviser Mike Waltz is not among them.

The dismissals come after Trump met in the Oval Office yesterday with conservative activist and conspiracy theorist Laura Loomer.

She reportedly brought a list of staff she deemed insufficiently loyal to the Trump agenda and urged the president to remove them.

The president, on Air Force One today, denied Loomer had anything to do with the ousters.

DONALD TRUMP, President of the United States: She is a very strong person.

And I saw her yesterday for a little while.

She has -- she makes recommendations on things and people.

And, sometimes, I listen to those recommendations, like I do with everybody.

I listen to everybody.

And then I make a decision.

AMNA NAWAZ: Also tonight, the Pentagon's acting inspector general says he will review Defense Secretary Pete Hegseth's use of the Signal messaging app.

He will look to determine whether Hegseth and other defense officials complied with DOD policies and procedures when they used the app to discuss attack plans against Houthi militants in Yemen.

The Senate has confirmed Dr. Mehmet Oz to lead the Centers for Medicare and Medicaid Services after a vote along party lines.

The agency he's stepping into provides health insurance to more than half of all Americans through Medicare, Medicaid and the Obamacare exchanges.

He will oversee annual spending of more than $2.5 trillion .

Dr. Oz, a former surgeon, TV personality and Senate candidate, sidestepped questions in his confirmation hearing about whether he would cut Medicaid to accommodate Republican plans to cut spending.

President Trump has been adamant he will not do so.

A string of violent storms across the Midwest and South has killed at least six people, and there's more weather on the way.

WOMAN: Oh, my God.

Somebody is losing all -- everything right now.

AMNA NAWAZ: Tornadoes tore across Arkansas yesterday, some of them with flashes of bright light as they ripped through power lines.

This morning, in places like Indiana, the damage was in full view.

Trees crashed through roofs and splayed across front yards.

Elsewhere, like in Southeast Michigan, lingering floodwaters left cars partly submerged.

The National Weather Service says more than 40 million Americans from Texas to Ohio could see catastrophic, potentially historic flash floods through the weekend.

Some areas could see well over a foot of rain.

Turning overseas now, the death toll in Myanmar from last week's deadly earthquake has climbed to more than 3,100 today, according to the military-run government.

Officials say that hundreds of people remain missing, though the number is feared to be much higher, this as the head of Myanmar's military regime made a rare visit to neighboring Thailand today, which is also reeling from Friday's quake.

General Min Aung Hlaing, who has been shunned by the West for overthrowing his country's democratically elected government in 2021, will try to garner international support.

The U.N. says more than three million people in Myanmar had been displaced due to armed conflict even before the quake hit.

Now to the Middle East, where over 100 more Palestinians across the Gaza Strip are dead tonight in one of the deadliest single days since fighting resumed between Israel and Hamas.

At least 27 of those killed were sheltering at a school in Northern Gaza when Israeli strikes rained down.

Our producer on the ground reports that family members of Hamas leaders appeared to be the intended targets.

Overnight, airstrikes killed at least 55 more people, mostly in the south.

Meanwhile, all of this happened as Israeli Prime Minister Benjamin Netanyahu received red carpet treatment with full military honors in Hungary.

Netanyahu, who faces allegations of war crimes in Gaza, traveled in defiance of an International Criminal Court warrant for his arrest.

Hungary's Prime Minister Viktor Orban says his country, once a party to the ICC, will no longer recognize it.

He called it a political tool.

And the court criticized the move.

Secretary of State Marco Rubio is in Brussels tonight attending a NATO meeting where he hoped to dispel any doubts about the U.S. commitment to the alliance.

Before meeting with other foreign ministers, he stood alongside Secretary-General Mark Rutte and was crystal clear about NATO, despite criticism and mixed signals from President Trump.

MARCO RUBIO, U.S. Secretary of State: The United States is as active in NATO as it has ever been.

And some of this hysteria and hyperbole that I see in the global media and some domestic media in the United States about NATO is unwarranted.

The United States -- President Trump has made clear he supports NATO.

We're going to remain in NATO.

AMNA NAWAZ: The meeting comes one day after President Trump announced sweeping new tariffs, causing global unease.

Trump's desire to reset relations with Russian President Vladimir Putin, as well as his intentions to control Greenland as U.S. territory, have also given NATO allies pause.

Thousands in Lithuania gathered today to send off the bodies of four U.S. soldiers who died during a training exercise in the Baltic nation last week.

A bugle sounded during the solemn farewell ceremony as four hearses carrying the soldiers left the capital of Vilnius before being flown to the United States for burial.

The U.S. Army has identified the soldiers.

They are Sergeant Troy Smith Knutson-Collins, Sergeant Jose Duenez Jr., Sergeant Edvin Franco, and Private 1st Class Dante Taitano.

Three of the soldiers were posthumously promoted to the rank of staff sergeant.

And, as they say, good things come in threes.

The Women's World Cup is poised to come back to the United States for the third time.

The decision isn't yet final, but today FIFA announced that the U.S. is uncontested to host the global tournament in 2031, possibly with Mexico's help, and the U.K. would then host in 2035.

Now, the U.S. has hosted before back-to-back tournaments in 1999 and 2003, but this time the competition will look different.

Beginning with the 2031 World Cup, the competition will expand from 32 teams to 48 teams.
