Sharon Lerner

Michael Kosta reports on the highs and lows of yesterday's primaries, the Supreme Court's ruling that makes it easier for politicians to accept bribes as "tips," and AI's effect on the music industry as record labels scramble to protect their artists from fake tunes. Plus, a helium-leaking spaceship from Boeing has left two astronauts stranded, and Ronny Chieng joins with updates from the ISS. ProPublica reporter Sharon Lerner sits down with Michael Kosta to discuss her latest piece in collaboration with The New Yorker on 3M's use and concealment of forever chemicals. They talk about how the company's secrets came to light, where people can find forever chemicals, and what it takes to be a good investigative journalist.
