In the day's other headlines: "Today Show" co-host Savannah Guthrie says her family is offering a $1 million reward for information leading to the recovery of her mother, Nancy.

In a video message, Guthrie said she and her family -- quote -- "still believe in a miracle" and hope her mother will be found alive, but they also acknowledge it may be too late.

SAVANNAH GUTHRIE, Co-Host, "The Today Show": We also know that she may be lost.

And if this is what is to be, then we will accept it.

But we need to know where she is.

AMNA NAWAZ: Guthrie also announced a $500,000 donation to the National Center for Missing and Exploited Children to support other families facing similar circumstances.

It's been more than three weeks since the 84-year-old Nancy Guthrie went missing from her Arizona home.

Authorities have received more than 20,000 tips, but have yet to make significant progress on finding those responsible.

Millions of people are still digging out from yesterday's winter storm that dropped record amounts of snow across parts of the Northeast.

Meteorologists called the storm the strongest in a decade, with more than two feet of snow blanketing much of New England.

Parts of Rhode Island got more than three feet shattering records.

Officials there have lifted a statewide travel ban, but say the cleanup could take a while.

GOV.

DANIEL MCKEE (D-RI): A full recovery is going to take time, but I can tell you the people behind me and the people that are out doing the work right now and doing everything they can to make sure that recovery is as quick as possible.

AMNA NAWAZ: Hundreds of thousands were still without power today, with more than 200,000 outages in Massachusetts alone, and roughly 2,200 flights were canceled, mostly in the New York area and Boston.

Officials say it could take days for full service to resume.

And, believe it or not, another storm is right around the corner.

This one is originating in the Great Lakes area and could deliver a few more inches of snow to areas already hard hit by this week's blizzard.

On Capitol Hill today, a bipartisan aviation safety bill failed in the House.

It would have required airplanes to carry locator technology, which federal investigators say could have prevented last year's midair collision near Washington that killed 67 people.

MAN: Two-thirds not being in the affirmative, the rules are not suspended and the bill is not passed.

AMNA NAWAZ: The so-called ROTOR Act fell just one vote shy of passing.

It breezed through the Senate back in December, but this week the Pentagon withdrew its support over cost and security concerns.

Instead, the military and airline groups have rallied around a new bill, which lawmakers say is more comprehensive, though it does not have the support of the National Transportation and Safety Board.

The Trump administration is suing the University of California for what it's calling an antisemitic, hostile work environment.

The lawsuit alleges that officials at its Los Angeles campus, or UCLA, -- quote -- "allegedly allowed virulent antisemitism to flourish on campus, harming students and staff alike."

It's the latest attempt by the Trump administration to punish the university for its handling of pro-Palestinian protests in 2024.

And it comes just months after the DOJ tried to cut research funding at UCLA and demanded more than a billion dollars to settle the charges, which the school has refused to pay.

Mexican President Claudia Sheinbaum says there is -- quote -- "no risk" to visitors planning to attend World Cup matches in her country following recent unrest sparked by the death of a major cartel figure.

Speaking to reporters today, Sheinbaum said security forces are working to restore order and that, as she put it, all the guarantees are in place for the tournament.

Her comments come after the death of the man known as El Mencho triggered roadblocks, fires and security clashes, notably in the Jalisco state.

Residents there are worried about losing tourism revenue, with the capital of Guadalajara set to host a number of the World Cup matches.

MARIA DOLORES AGUIRRE, Tapalpa, Mexico Resident (through translator): The government is going to have to have a lot of security.

I think it will have an impact because everyone just saw what happened.

And, of course, people are going to think twice about coming.

Yes it will have an impact.

AMNA NAWAZ: At least 70 people died in the operation that led to El Mencho's death and its aftermath.

A number of international tourists also found themselves trapped in the affected areas and the U.S.

State Department issued a shelter-in-place advisory, though that has since been lifted and flights have resumed.

The director of the Louvre Museum is stepping down months after a shocking jewel heist at the world's most visited museum.

Laurence des Cars had faced increasing criticism since last October's brazen heist, when burglars made off with an estimated $102 million worth of crown jewels.

The theft exposed security gaps at the Louvre.

And, at the time, des Cars offered to resign, but was refused.

Today French President Emmanuel Macron accepted her resignation, calling it -- quote -- "an act of responsibility at a time when the world's largest museum needs calm."

On Wall Street today, stocks rebounded after Monday's losses.

The Dow Jones industrial average added 370 points on the day.

The Nasdaq rose more than 230 points, or around 1 percent.

We're college men now.
