The Rev. Dr. C.T. Vivian was described by Dr. Martin Luther King, Jr., as “the greatest preacher to ever live.” Journalist Steve Fiffer talks with In Focus host Carolyn Hutcheson about Vivian’s training in nonviolence and his legacy as a tireless Civil Rights leader. In 2013, he received the Presidential Medal of Freedom. Fiffer, a friend of Vivian, completed the preacher’s memoir.
