AMNA NAWAZ: In the day's other headlines, Health Secretary Robert F. Kennedy, Jr. says the CDC will no longer recommend COVID vaccines for healthy children and pregnant women.

Kennedy made the announcement in a video message on social media, standing alongside the FDA commissioner and the head of the National Institutes of Health.

No one from the CDC was featured.

The new policy jumps ahead of a planned meeting next month by a CDC panel to address shots for the fall.

It also follows the decision by the FDA last week to require new data before approving booster shots for healthy adults and kids.

Today's announcement could affect how doctors advise their patients on the vaccines and how insurers cover them.

The Trump administration is directing federal agencies to cancel all remaining contracts with Harvard University totaling about $100 million.

That's according to a letter from the General Services Administration.

The government has already cut more than $2.6 billion in federal research grants for the school, which President Trump has accused of fostering antisemitism and having a liberal bias.

Today's action follows weeks of increasing tensions involving Harvard's hiring practices, its tax-exempt status, and its ability to enroll international students, among others.

In the U.K., police say they have arrested a 53-year-old British man on suspicion of attempted murder following a car ramming yesterday at a Liverpool soccer parade.

Forensic officers were at the scene of the crash today, where hundreds of thousands of people had gathered to celebrate Liverpool's Premier League championship.

Authorities say 11 of the 50 people who were hospitalized are still there receiving treatment, but are in stable condition.

Fans are still grappling with how a day of festivity turned into tragedy.

AARON JONES, Liverpool Parade Attendee: Such a shame.

It's just ruined it for everyone, really.

It's supposed to be celebrations.

And, instead, the day is always going to be remembered for this now, instead of the trophy parade, like it was supposed to.

AMNA NAWAZ: Authorities are not treating the incident as terrorism and believe the suspect may have been driving while on drugs.

King Charles III opened Canada's Parliament this morning, saying the commonwealth member is facing a critical moment.

Charles received a warm welcome in Ottawa with music and pageantry.

He was invited by Prime Minister Mark Carney to deliver the so-called Speech from the Throne amid threats from President Trump that the U.S. annex Canada.

In comments largely written by Carney's government, Charles told the assembly that -- quote -- "The true north is indeed strong and free."

KING CHARLES III, United Kingdom: All Canadians can give themselves far more than any foreign power on any continent can ever take away, and that, by staying true to Canadian values, Canada can build new alliances and a economy that serves all Canadians.

AMNA NAWAZ: Charles was the first British monarch to personally deliver the Throne Speech since his mother, Queen Elizabeth II, did so in 1977.

The Supreme Court rejected an appeal today from a Massachusetts student who was barred from wearing a T-shirt that said - - quote -- "There are only two genders."

Instead, the justices let stand a lower court's ruling that the ban did not violate the student's free speech.

Local school officials had argued that the wearing of the shirt would have a negative impact on transgender and gender non-conforming students.

Separately, the justices also declined to hear an appeal from a Native American group to stop a copper mining project on land it considers sacred.

The dispute centers on the transfer of federal land in Arizona known as Oak Flat to a subsidiary of mining giants Rio Tinto and BHP.

The company says the project will create thousands of jobs.

On Wall Street today, stocks jumped as investors got their first chance to react to President Trump's delay over the weekend of his European tariffs.

The Dow Jones industrial average added more than 700 points on the day.

The Nasdaq rose about 460 points, or nearly 2.5 percent.

The S&P 500 also ended sharply higher.
