I'm Amna Nawaz.

GEOFF BENNETT: And I'm Geoff Bennett.

On the "NewsHour" tonight: The House intelligence chairman issues an urgent warning about a

national security threat and calls on the White House to declassify the information.

AMNA NAWAZ: The political fallout from the historic impeachment of Homeland Security

Secretary Alejandro Mayorkas.

GEOFF BENNETT: And in this consequential election year, Judy Woodruff visits a mock presidential

convention to hear what college-age voters think about the candidates and the nation's

deep divisions.

ROBERT MISH, Student, Washington and Lee University: I think there's a spotlight on that polarization

now, and people are kind of opening their eyes and being like, wow, is this healthy

for our country?

(BREAK)

AMNA NAWAZ: Welcome to the "NewsHour."

One person is dead tonight and up to 15 hurt after Kansas City's Super Bowl victory parade

ended in a burst of gunfire.

GEOFF BENNETT: It's unclear how many of the injured have gunshot wounds, but police say

two suspects were arrested.

A sea of red and gold had flooded the city's downtown as players paraded on double-decker

buses.

Then shooting broke out near the scene and people in the crowd, including the mayor,

started running.

WOMAN: All of a sudden, people started crushing forward.

Everybody started running.

There was screaming.

We didn't know what was happening, but, in this day and age, when people run, you run.

And so I put my arms around her, and we tried to push through, so people wouldn't run on

top of us.

And there was a woman crying, saying something about somebody had been shot.

GEOFF BENNETT: The Chiefs said their players were already on buses heading back to their

stadium when the shooting started.

Police had no initial details on what the motive might have been.

In the day's other headlines: Ukraine's military announced it attacked and sank a Russian worship

in the Black Sea using naval drones.

It happened a few miles off the coast of Crimea near Alupka.

Russia annexed that peninsula back in 2014.

The Ukrainians released night-vision video purportedly showing an explosion that blew

a hole in the side of the amphibious landing ship.

The vessel could then be seen turned on its side.

It's the second time in two weeks that Ukraine has claimed it sank a Russian ship.

Family members of Israeli hostages urged prosecutors at the International Criminal Court today

to go after Hamas leaders.

They argued that heads of the group should be charged and arrested for genocide and other

crimes in the October 7 attacks in Southern Israel.

At a rainy news conference at The Hague, the hostage relatives demanded accountability

and justice for those still held in Gaza.

YAMIT ASHKENAZI, Sister of Israeli Hostage: The world must wake up.

The world needs to know that my sister is in a tunnel somewhere cold and hungry, without

medication, and exposed to sexual violence for 131 days.

GEOFF BENNETT: The court's chief prosecutor says he's already investigating alleged crimes

committed by both sides in the war.

Here at home, New York's highest court heard Harvey Weinstein's appeal today of his landmark

rape conviction.

The former movie mogul's case came at the dawn of the MeToo movement.

His lawyers argue that Weinstein was denied a fair trial because the judge succumbed to

intense pressure to make an example of him.

He's currently serving a 23-year sentence in state prison.

Thousands of Uber and Lyft drivers staged a Valentine's Day strike across the U.S. and

Britain today.

Workers in Chicago and elsewhere hit the picket lines demanding better pay, benefits and working

conditions.

They also rallied outside major airports to voice their frustration.

JOCILYN FLOYD, Uber Driver: Uber has proven time and time again that they're putting profits

over people, right?

In shareholder meetings, they discuss profits.

There's no question about safety, protection from deactivation or compensation.

Drivers have been losing money for years.

GEOFF BENNETT: The one-day strike was time to cut into Valentine's traffic tonight, but

Uber said it does not expect the walkout to have much impact.

And, on Wall Street, stocks recovered from Tuesday's sell-off.

The Dow Jones industrial average gained 151 points to close at 38424.

The Nasdaq rose 203 points, and the S&P 500 added 47.

Still to come on the "NewsHour": a former general linked to human rights abuses claims

victory in Indonesia's presidential election; amid concerns about Biden and Trump's age,

experts weigh in on how getting older affects our memory; and Judy Woodruff speaks with

young voters about the divisive political climate in this election year.

It was a rare alarming public statement.

One of the handful of members of Congress with the most access to America's secrets

warned today of a -- quote -- "serious national security threat."

Congressional leaders have since described it as a -- quote -- "serious, but not urgent

matter."

Still, the warning rattled Washington and beyond, as U.S. officials at the same time

worked to find at least a pause to the war in Gaza.

Nick Schifrin is here following all of these developments and joins us now.

So, Nick, what do we know about this national security threat?

NICK SCHIFRIN: Two officials confirmed to me that Russia recently showcased a new capability

in space, Geoff.

That is what this threat is all about.

Russia regularly launches space -- has space launches.

You see one right there.

And the officials describe that Russia recently launched a new anti-satellite capability,

meaning a satellite that can attack other satellites.

The officials tell me that this satellite, which is possibly nuclear-powered, has an

electronic warfare capability to target American satellites that are essential for U.S. military

and civilian communication.

Now, that public statement that you just referred to right there was from Mike Turner, the chairman

of the House Intelligence Committee.

You see him right there.

He is a voice for stronger national security, especially for Ukraine, which itself right

now is facing serious threats from Russian electronic warfare.

And, of course, this comes as members in the House, especially in the Republican Caucus,

are resisting some support for Ukraine against Russia in the ongoing war there.

After this statement was released by Turner, Jake Sullivan, the national security adviser,

acknowledged that he was actually supposed to brief Turner and others tomorrow about

this matter.

The Intelligence Committees had this intelligence about two to three weeks ago, according to

the officials I speak to.

And they say that, while it is very, very important, it is not in any way imminent,

as we heard Speaker of the House Mike Johnson admit today.

REP.

MIKE JOHNSON (R-LA): Last month, I sent a letter to the White House requesting a meeting

with the president to discuss a serious national security issue that is classified.

I want to assure the American people there is no need for public alarm.

We are going to work together to address this matter, as we do all sensitive matters that

are classified.

And, beyond that, I'm not at liberty to disclose classified information and really can't say

much more.

NICK SCHIFRIN: No public alarm, Geoff, but, clearly, a concern that the U.S. has had for

a long time about Russia's anti-satellite capabilities is clearly much higher with this

new capability.

GEOFF BENNETT: All right.

Well, let's shift our focus to the Israel-Hamas war, which you're also tracking.

Israel's prime minister appeared to take a hard line in negotiations that would pause

the war to allow for the release of some Israeli hostages.

What's the latest there?

NICK SCHIFRIN: Netanyahu today repeated his hard line that he has said multiple times,

one, that there needs to be military pressure on Hamas in Southern Gaza in order to make

any progress on hostages.

And he also again called Hamas' demands when it came to the hostages -- quote -- "delusional."

And so where we are is that Israel continues to have the hard line.

But U.S. officials privately say that Netanyahu is allowing progress to be made on the hostage

deal and that negotiations are ongoing, especially after a meeting yesterday in Cairo with Israeli

U.S. spy chiefs and other diplomats.

And so this is where we are on the hostage deal.

As we recall, two weeks ago, Israel agreed to a plan negotiated by the U.S., Qatar and

Egypt to an initial six-week pause with three phases of hostage releases and three phases

of pauses in the war.

Hamas' counterproposal last week required an Israeli withdrawal from cities first and

then from all of Gaza.

Israel interpreted that as Hamas remaining in power.

So where are we publicly?

Netanyahu takes a hard line, and that helps him keep pressure militarily on Hamas, which

the U.S. does believe helps in these hostage negotiations.

It also helps relieve pressure on Netanyahu within his own government, because, of course,

his own coalition among the right wing, they don't want him to stop this war, and they

don't want him to make a deal that would release hostages if it means the end of the war before

Hamas is destroyed.

So the bottom line, U.S. officials will believe that Netanyahu will allow progress to be made

on the hostages as he threatens an assault on Rafah.

That is the city in Southern Gaza where 1.3 million Gazans have fled.

And the question tonight is, will Netanyahu allow more progress to be made first, or will

there be an assault on Rafah?

GEOFF BENNETT: Yes.

Well, bring us up to speed on Israel's effort in terms of taking out Hamas' leadership.

NICK SCHIFRIN: So, the target in Rafah right now, Geoff, is what Israel calls the final

four battalions of Hamas' military capacity.

The target in Khan Yunis, where Israel has been fighting ferociously for weeks, is underground.

And that is the tunnels where Israel believes the leadership of Hamas is hiding.

And Israel released yesterday this video that it says shows the leader of Hamas, Yahya Sinwar,

who walked out there, right there -- you see that, that's an Israeli animation there -- walking

out with his family, with his children, and with his wife underneath a tunnel in Khan

Yunis on October the 10th.

And what Israel says is that Yahya Sinwar was surrounded by millions of dollars, as

well as civilians.

But above ground, in Khan Yunis, Israel continues the assault.

Today, it ordered the evacuation of Nasser Hospital.

And just this afternoon, Doctors Without Borders today criticized that evacuation order, saying

that -- quote -- "The people inside have nowhere to go."

Either they become an Israeli target in the hospital or enter a -- quote -- "apocalyptic

landscape outside of it."

GEOFF BENNETT: Nick Schifrin, thanks so much for that reporting.

We appreciate it.

NICK SCHIFRIN: Thank you.

AMNA NAWAZ: Homeland Security Secretary Alejandro Mayorkas became the first presidential Cabinet

member to report to work the day after getting impeached.

House Republicans eked out exactly the votes they needed to pass the articles in a 215-214

vote.

Lisa Desjardins joins me now to help us understand what comes next and why Republicans will soon

have even more difficulty passing their agenda.

So, Lisa, let's start with impeachment, another rare moment in U.S. history.

What happens now?

LISA DESJARDINS: OK, let's talk about here.

A reminder of what was passed by -- narrowly, the most narrow margin possible in the House,

last night.

The impeachment articles, there are two.

House Republicans in these articles accuse Secretary Mayorkas of two things.

They say willful and systemic refusal to comply with the law and breach of public trust.

As you read the 20 pages of the articles, really, what they're accusing him of is a

litany of grievances about the border crisis itself.

There has not been any direct evidence that he himself went out of his way to make sure

that laws were broken.

And we know that some Border Patrol associations have said, in fact, they think things have

gotten better.

Not everyone agrees with that.

But this will be a question going forward for the Senate.

The other public trust breach was Republicans say he lied to Congress.

He says, no, that was a semantic argument over whether the border is, in fact, something

that is secure or not.

So, OK, let's talk about what's next.

That's where we're at.

This will move to the Senate.

It will move to the Senate in about two weeks.

Here's the timeline.

February 26, the managers appointed by Republicans will carry the impeachment articles over to

the Senate.

Then, the next day, senators will be sworn in as jurors for this potential trial.

Now, here's what's interesting, Amna.

The Democrats and Leader Schumer's office believe that there could be other options

here to either hold a short trial or move to dismiss this altogether.

This is an area of constitutional law that we don't encounter a lot.

What might be important here is where Senate Republicans are, of course.
