Good evening. I'm Jeff Bennett.

And I'm Amna Navaz on the news hour tonight.

Meta CEO Mark Zuckerberg takes the stand in a landmark trial on the addictive nature of social media.

We hear from a parent about the risks to kids.

These social media companies are designing them in a way that are addicting our children,

and they are operating with complete impunity.

The U.S. says it will further reduce its true presence in Syria after fighting ISIS there for the last decade.

And the immigration crackdown in the Twin Cities creates long-term uncertainties for the area's

teachers and students.

I'm trying to overcome.

I'm trying to just go on without it, but the more it hits me, the more I get sad and scared. Welcome to the news hour.

Meta CEO Mark Zuckerberg took the stand in a Los Angeles federal court

today to defend his company and its platform Instagram against allegations it was deliberately

designed to be addictive to children and teens. It's the first time he's testified about child safety in

front of a jury. The trial focuses on a now 20-year-old woman, known by her initials, KGM,

who says she became addicted to social media as a young girl, and that excessive use exacerbated

her depression, anxiety, and suicidal thoughts. At issue is whether tech companies, despite knowing

it would cause psychological harm, intentionally designed their social media platforms to hook young users with addictive features like Infinite Scroll, personally tailored algorithms, and push notifications.

YouTube is also included in the lawsuit. TikTok and Snapchat chose to settle before the trial started.

The outcome will have big implications for some

1600 similar cases across the country and could lead to monetary damages or force major

changes to the platforms themselves. For more, we're joined now by NPR tech correspondent Bobby Allen.
