Sen. Doug Jones made history when he became the first Democrat to win a U.S. Senate seat in Alabama in 25 years. Before that, as a U.S. Attorney, Jones focused on righting a historic wrong: the unsolved 1963 bombing of the 16th Street Baptist Church in Birmingham. Four black girls were killed while they were getting ready for church. The first bomber was convicted in 1977. Nearly 40 years after the attack, Jones won the conviction of two more bombers in 2001 and 2002. Jones joins "CBS This Morning" to discuss his new book, "Bending Toward Justice: The Birmingham Church Bombing That Changed the Course of Civil Rights."
