Only on the "CBS This Morning" podcast, former CNN anchor Isha Sesay joins CTM's Vladimir Duthiers to discuss her new book, "Beneath the Tamarind Tree: A Story of Courage, Family, and the Lost Schoolgirls of Boko Haram." Sesay and Duthiers, a former CNN international correspondent based in West Africa, reflect on their coverage of the 2014 Boko Haram kidnapping of 276 schoolgirls from the Chibok Government Secondary School in northeastern Nigeria. Sesay recalls pressuring government officials for answers when they provided little information on the abduction and their efforts to find the girls. She shares why she stayed on the story for years, long after the viral #BringBackOurGirls stopped trending and dozens of the girls were returned to their families. Plus, Sesay explains her decision to leave CNN and launch the organization W.E. (Women Everywhere) Can Lead, dedicated to empowering teenage girls to become Africa's next generation of leaders.
