New York Senator Chuck Schumer today called for an investigation of the FAA's handling of the situation at Newark and across the country.

SEN. CHUCK SCHUMER (D-NY): To say that there is just minor turbulence at Newark Airport and the FAA, that would be the understatement of the year.

In a memo obtained by the "News Hour," Hegseth called for a 20 percent reduction of four-star generals across the active-duty military.

He also ordered the National Guard to cut 20 percent of its top positions.

Only 44 of those are four-star general or flag officers.

As of today, federal education officials are restarting efforts to collect on student loans that are in default.

Borrowers had enjoyed a pause on such collections that started during the COVID pandemic.

More than five million people are currently in default.

Officials could withhold tax refunds or Social Security benefits and garnish wages to recover the debt that is owed.

Those who are in default are urged to contact the Default Resolution Group within the Office of Federal Student Aid.

The plea deal calls for Walrath to get a 15-year prison term.

He will be sentenced in August.

Romania's prime minister announced his resignation today after his party's candidate failed to advance in a redo of the country's presidential election.

Hard-right nationalist George Simion far outpaced the other contenders, winning more than 40 percent of Sunday's vote.

He will face pro-Western reformist Nicusor Dan in a run-off later this month.

Simion ran on a nationalist platform and is a vocal supporter of President Trump.

He thanked his backers in a social media video today.

GEORGE SIMION, Romanian Presidential Candidate (through translator): Your thirst for freedom has triumphed.

It is your victory, not mine, and it will continue to triumph.

Your vote today is an outstretched hand to the country you miss.

The Romania you want to return to, we will build together.

And Skype officially goes offline today.

For more than two decades, the Internet calling service connected people from around the world.

At one point it had more than 300 million users, but competition from the likes of zoom and WhatsApp ate into Skype's popularity.

Skype for Business, which is a separate service, will carry on.

Still, it's the end of an era.
