Why LBJ and MLK needed each other

In 1964, President Lyndon Johnson signed into law the Civil Rights Act with The Rev. Martin Luther King Jr. standing at his side. Peniel Joseph is the Barbara Jordan Chair in Political Values and Ethics at the LBJ School of Public Affairs and professor of history and the founding director of the Center for the Study of Race and Democracy at the University of Texas at Austin. He joins host Krys Boyd to discuss the contentious but essential relationship between the president and Civil Rights leader. His essay appears in the book “LBJ’s America: The Life and Legacies of Lyndon Baines Johnson.”
