The MLK and LBJ tapes [audio 5min]

This weekend is the start of Black History Month and we thought we'd take a look back at the working relationship between Dr. Martin Luther King, Jr., and President Lyndon B. Johnson. Both historical figures have been raised recently in the contest between Senators Clinton and Obama as they vie for the democratic presidential nomination. But we thought, what about it? How did President Johnson and Martin Luther King, Jr., actually work together? Joining us is historian Nick Kotz. He wrote a book called Judgment Days: Lyndon Baines Johnson, Martin Luther King, Jr., and the Laws that Changed America.
