AMNA NAWAZ: The day's other headlines start at Harvard University.

The school announced this afternoon that it will review academic offerings and admissions policies in response to a pair of internal reports about antisemitism and Islamophobia on campus.

Harvard's president, Alan Garber, commissioned the reports following last spring's pro-Palestinian protests.

Garber wrote today that he wants to -- quote - - "ensure that Harvard University is a place where ideas are welcomed, entertained, and contested in the spirit of seeking truth."

It comes as the university fights a legal battle with the Trump administration, which froze billions of dollars of federal funding amid accusations of antisemitism at campus protests.

Well, the lights are almost fully back on in Spain and Portugal after yesterday's massive blackout, but it's still not clear what caused the outage.

In Spain, more than 99 percent of energy demand has been restored.

Today, train stations in Madrid were packed as stranded passengers tried to get home.

Emergency workers in Spain say nearly 35,000 people had to be rescued along railways and underground.

Speaking today, Spain's prime minister dismissed claims that the blackout was caused by a cyberattack and said officials are investigating the cause.

PEDRO SANCHEZ, Spanish Prime Minister (through translator): The government of Spain is going to get to the bottom of this matter.

Reforms will be made and necessary measures will be taken to ensure this does not happen again.

And, obviously, we will demand the relevant responsibilities from all private operators.

Spain lost the equivalent of 60 percent of its national energy demand in just five seconds, knocking out transit, banking, and phone services, among others.

Here at home, the Senate today confirmed David Perdue as President Trump's U.S. ambassador to China.

Perdue is a former business executive who served a single term as a Republican senator from Georgia.

He steps into the job in the middle of a tense tariff war between the two largest economies in the world.

China's military actions in the Indo-Pacific have also deepened its strategic rivalry with the U.S. At his confirmation hearing earlier this month, Perdue described the U.S. relationship with China as the -- quote -- "most consequential diplomatic challenge of the 21st century."

The Trump administration has dismissed many of former President Joe Biden's nominees to the board that oversees the U.S.

Holocaust Memorial Museum here in Washington, D.C. That includes Doug Emhoff, the husband of former Vice President Kamala Harris.

On the West Coast, Los Angeles County workers walked the picket line today to demand higher wages.

The workers showed up by the tens of thousands, the first time ever that all of L.A. County's union members went on strike.

The two-day stoppage could mean closures or disruptions to many critical government services in a county that's home to some 10 million people.

The government there says it's facing unprecedented stresses and has little room in its budget for increased pay.

The union's last contract expired in March.

A prosecutor told a court in England today that the famous Sycamore Gap tree was cut down in a deliberate and mindless act.

The majestic landmark once sat between two hills along the ancient Hadrian's Wall in Northern England.

In a ceremony this afternoon at the Capitol, House Speaker Mike Johnson said the honor was long overdue.

REP. MIKE JOHNSON (R-LA): They got the job done, even in the face of inadequate supplies and even in the face of discrimination, both within the Army and back home.

These women were valiant members of our Greatest Generation.

AMNA NAWAZ: The Six Triple Eight inspired generations of Black women to join the military and were the subject of a documentary and also a feature film starring actress Kerry Washington.
