Journalist and author Souad Mekhennet joins us to discuss her new book I Was Told to Come Alone: My Journey Behind the Lines of Jihad. Born in Germany to Muslim parents, Mekhennet's background and skills have brought her access to members of ISIS, Al-Qaeda and others who would normally not speak with Western journalists. Mekhennet travels from Germany where the 9/11 plotters were radicalized to the Turkish-Syrian border where ISIS is fighting for control.
