The republican presidential candidates face off tonight in their second debate. Two Northwestern University grads with a keen interest in the event are behind a Donald Trump PAC based in Chicago. We hear more about why they think the mogul needs support from millennials in the Windy City. We’ve also got two notable photographers in studio who captured some of rock music’s best moments from the late 1960’s and early 70’s. Henry Diltz and Pattie Boyd are on tour with many of those photos. They’re at City Winery this evening. Plus, Chicago jazz legend George Freeman is in our Jim and Kay Mabie Performance Studio along with his saxophone playing nephew Chico Freeman. They’ve got a new album.
