This is the Brian Lairn Show on WNYC.

I'm Bridget Bergen, senior reporter in the WNYC and Gothamist Newsroom.

Filling in for Brian today, happy Groundhog Day to all who celebrate. Maybe you already

heard, but our local rodent, Staten Island Chuck, did not see his shadow. So as the legend goes,

we'll be having an early spring. Hooray. On today's show, Manhattan Borough President Mark Levine

joins us. He's got a proposal to remove old sidewalk sheds that seem to linger outside some

buildings for years. We'll talk to him about that and a few other city issues. Plus, later in the show,

Craig Newmark, he's the Craig of Craigslist. We'll be here along with Grasiello-Machovsky,

who is the dean of the journalism graduate school at CUNY. They'll tell us about a big donation from Craig's Foundation that will allow the school to soon go completely tuition-free. Amazing. And we'll wrap up today's show with a call-in for anyone who works a four-day work week. Whether you're cramming five days of work into four or

working reduced hours, we want to hear how the four-day work week is going for you. But first,

senators called on the CEOs of five major tech platforms to testify before them on the issue of

child safety online this week.

Featuring testimony from the bosses of Mehta, the parent company of Facebook, TikTok, Snapchat,

Discord, and X, formerly known as Twitter, the scene was what some of us have come to expect from

these high-profile hearings. Sedators grilled these tech giants on the lack of transparency

when it comes to social media and the harm

it could potentially cause kids.

But this time, they focused pointedly

on child sexual exploitation.

To add to the highly charged atmosphere,

survivors of exploitation and family members of victims were in the audience.

Here is Senator Dick Durbin with his opening remarks referencing something called CSAM, which stands for child sexual abuse material.
