Half a century later, those who marched on Washington

Clarence B. Jones, a chief speechwriter for Martin Luther King Jr.’s “I Have A Dream” speech at the March on Washington, reads his favorite passage from “Letter From Birmingham Jail” just feet away from King’s Birmingham jail cell.

Jones, King’s legal counsel during his 1963 jail stint in Birmingham, helped smuggle King’s writings, which were on newspaper margins and toilet paper, in and out of the jail. The end result would be the most important piece of literature from the Civil Rights Movement.

Later this month, we will look back on the people behind the editing and production process of "Letter From Birmingham Jail" and their legacies on the 50th anniversary of the March on Washington. Watch our coming report on America Tonight.
