Controversial activist and former death row inmate Mumia Abu-Jamal recently recorded a message to the organizers of the Occupy The Justice Department action that took place in April. In the short audio clip, Abu-Jamal encourages everyone to "Keep on rolling, keep on moving and while you do it, treat each other as brothers and sisters, companeros y companeras."

For more of Mumia's thoughts on Occupy, education and radical social movements, check out his "Message To The Movement" pamphlet as part of the Occupied Media Pamphlet series.
