Tucker Carlson, Don Lemon, And The Future Of Cable News

Tucker Carlson’s firing Monday by Fox News sent shockwaves through the cable news landscape -- and the conservative media world. One of the network’s best-known hosts, Carlson attracted massive audiences and wielded real political power, with a direct line to the White House and Donald Trump, when he was in office. Shortly after word of Carlson’s departure leaked, another cable news star grabbed headlines. Longtime CNN host Don Lemon announced the network cut him loose, just weeks after he made waves with on-air sexist remarks. So what do these high-profile exits say about the state of Fox, CNN, cable news and our information ecosystem more generally? NPR media correspondent David Folkenflik joins Diane to discuss.
