On this the 40th anniversary of the assassination of Malcolm X, we spend the hour with historian Manning Marable who has spent a decade working on a new biography of Malcolm X. He is one of the few historians to see the three missing chapters from “The Autobiography of Malcolm X” that he says paint a very different picture than the book with Alex Haley and Spike Lee’s film. Marable has also had unprecedented access to Malcolm’s family and documents that shed new light on the involvement of the New York Police, the FBI and possibly the CIA in Malcolm X’s assassination. Manning today called on the federal government to release all remaining classified documents on Malcolm X. [includes rush transcript]
