TERRY GROSS, HOST:

This is FRESH AIR. I'm Terry Gross. The nation's attention is riveted on the drama unfolding in Washington, where House investigators are assembling evidence for their impeachment inquiry, and President Trump is refusing to cooperate. Our guest, Bloomberg Businessweek columnist Joshua Green, says that, ironically, Trump's impeachment peril is the unintended result of an effort to help him.

In 2013, Edward Snowden was an IT systems expert working under contract for the National Security Agency when he traveled to Hong Kong to provide three journalists with thousands of top-secret documents about U.S. intelligence agencies' surveillance of American citizens.

More than 70,000 Americans died from drug overdoses last year, and a growing number of those deaths are attributed to the powerful synthetic opioid fentanyl. Journalist Ben Westhoff says the drug, while an important painkiller and anesthesia medicine in hospitals, is now killing more Americans annually as a street drug than any other in U.S. history.

Nearly 2,000 cities, towns and counties across America are currently participating in a massive multidistrict civil lawsuit against the opioid industry for damages related to the abuse of prescription pain medication. The defendants in the suit include drug manufacturers like Mallinckrodt, wholesale distributors McKesson and Cardinal Health, and pharmacy chains CVS and Walgreens.

Diver and photographer Jill Heinerth has explored unmapped, underwater caves deep in the earth, as well as the submerged crevices of an iceberg. She has seen hidden creatures and life forms that have never been exposed to the light of day.

"Since I was the smallest child, I always wanted to be an explorer — to have an opportunity to go someplace where nobody has ever been before," she says. "As an artist with my camera, it's an incredible opportunity to document these places and bring back images to share with others."
