Only on the "CBS This Morning" podcast, "CBS Sunday Morning" correspondent Mo Rocca joins "CBS This Morning" co-host Bianna Golodryga to discuss his new podcast, "Mobituaries." Rocca provides "mo-bits" for well-known figures like Audrey Hepburn and Sammy Davis Jr., who he says didn't get proper send offs the first time around. Plus he celebrates the lives of those who have been forgotten with time, like JFK impersonator Vaughn Meader, whose career died with the assassination of the president. Rocca explains why he decided to create "mobituaries" for social movements, civilizations and even a pair of trees. He also shares what he hopes will be the first line of his own mo-bit.
