Only on the "CBS This Morning" podcast, Andrew Tisch and Mitchell Gold join "CBS This Morning" co-host Gayle King to discuss the importance of immigration and their new book, "Journeys: An American Story." Tisch explains why he decided to compile 72 stories - from such notable figures as Tony Bennett, Marlo Thomas and Nancy Pelosi - about their journey to America. Tisch, the co-chairman of Loews Corporation, shares his family's own story of immigrating to America and building a billion-dollar family-run company. Gold, co-founder and chairman of Mitchell Gold + Bob Williams, also shares his family's story of coming to the United States, becoming an entrepreneur and fighting for LGBTQ equality.
