In California, at least 19 people have died as storms continue to batter the region, leading to widespread flooding, mudslides and power outages. The National Weather Service says large portions of Central California have received over half their annual normal precipitation in just the past two weeks — and more rain is coming. The National Oceanic and Atmospheric Administration says 34 million Californians are under a flood watch.

We speak with journalist Lynzy Billing, whose investigation for ProPublica details how CIA-backed death squads, known as Zero Units, have yet to be held accountable for killing hundreds of civilians during the U.S. War in Afghanistan. The Afghan units, which were routinely accompanied by U.S. soldiers, became feared throughout rural Afghanistan for their brutal night raids, often descending upon villagers from helicopters and carrying out summary executions before disappearing.

We go to Kabul to speak with Jan Egeland of the Norwegian Refugee Council about the deteriorating security situation in Afghanistan, where at least five people died Wednesday in a suicide bombing near the Foreign Ministry.

We speak with civil rights leader Ben Jealous about his new memoir, “Never Forget Our People Were Always Free,” which examines his long career as an activist and organizer, and growing up the son of a white father and a Black mother. He discusses the lessons he drew from his mother, Ann Todd Jealous, and his grandmother, Mamie Todd, about the racism they experienced in their lifetimes.

As ceremonies mark the 100th anniversary of when a white mob attacked and burned down the Black town of Rosewood, Florida, we look at the largely untold story of how a racist mob murdered at least six Black residents and forced the rest of the town to flee.

We speak with one of the 7,000 nurses on strike now in New York City at two hospital systems that account for more than a quarter of all hospital beds in the city, and a journalist who has documented how hospital CEOs are boosting their own pay by millions of dollars while slashing charity care. The strike began Monday after nurses failed to reach a new contract agreement with Mount Sinai Hospital and Montefiore Medical Center, with higher wages and better staffing among their main demands.
