JOHN YANG: In tonight's other news, an investigation is underway after a car plowed into a crowd outside a Los Angeles nightclub, injuring dozens.

The driver veered onto a sidewalk and crashed into a taco truck and valet stand before hitting pedestrians.

Firefighters on the scene say the driver may have lost consciousness before losing control of the car.

Thirty people were injured, three of them critically.

In Gaza, at least 32 people are dead after Israeli troops fired toward a crowd at a food aid site.

It happened near the distribution site run by the controversial Gaza Humanitarian Foundation.

The Israeli military said it fired warning shots when people approaching them ignored orders to stop.

Witnesses said the situation is going increasingly desperate and dangerous.

SANAA AL-JABERI, Witness (through translator): We said, let's go get flight and bring food from what they're distributing.

We stood and the sites opened with a sign that said we're allowed in.

And people started running.

And when people started running, they besieged us with tanks and snipers and started shooting young men in a hysterical way.

Is this food or death?

Why they don't talk with us, they only shoot us.

JOHN YANG: All four of the Gaza Humanitarian Foundation aid distribution sites are in areas controlled by the Israeli military.

The United Nations said a lack of humanitarian aid has led to preventable deaths.

Big changes are in the works at the Environmental Protection Agency as part of the Trump administration's drive to shrink the federal workforce.

Late Friday, the EPA announced the closing of its research branch, which provides scientific data linked to protecting the environment and human health.

Instead, research will be conducted by the Office of Applied Science and Environmental Solutions.

EPA Administrator Lee Zeldin said the move will save $748 million and Edwin J. Feulner, a prominent figure in the American conservative movement, has died.

Feulner was the founder and longtime leader of the conservative think tank The Heritage Foundation.

Feulner grew up in the Chicago suburbs, raised as a devout Catholic.

He studied economics and founded The Heritage foundation in 1973.

He said its goal was to offer alternatives to failed liberal policies.

It helped shape the policies of the administrations of Ronald Reagan and now, through Project 2025, President Trump.

Edwin J. Feulner was 83 years old.

Still to come on PBS News Weekend, how major funding cuts at the world's premier cancer research center could affect the fight against the disease and the newest additions to the list of World Heritage sites.

Just in time for summer travel.
