Jon and Tracey Stewart share new mission with "Do Unto Animals"
After "The Daily Show," Stewart and his family traded in their New York City life for one on the farm with four dogs, two pigs, three rabbits, two guinea pigs, one bird and two fish. If you want more proof of their love for animals, his wife Tracey is out with her first book called "Do Unto Animals." Only on "CBS This Morning," Gayle King visited the Stewarts at their farm for their first interview together.
