Host Scott Tong speaks to Merav Raviv and Itay Raviv, who came to Washington D.C. from Israel to plead for international action to negotiate the safe return of family captured by Hamas in the Oct. 7 attacks. And, prolonged drought and overuse have brought the Great Salt Lake in Utah to the brink of collapse, threatening the lives of the animals and the people who live there. Here & Now's Peter O'Dowd reports. Then, Robert "Mack" McCormick's massive and closely held collection of blues music and research from the 1950s and 60s is seeing the light of day.
