Manufacturers of Unmanned Aerial Vehicles, also known as drones, visited members of Congress today on Capitol Hill. Corporate members of the Association for Unmanned Vehicle Systems International (AUVSI) put on a drone expo for representatives from the House Congressional Unmanned Systems Caucus. Protestors from CODEPINK were on hand to greet AUVSI representatives as they entered the Rayburn Building. CODEPINK’s co-founder Medea Benjamin has been an outspoken critic of the Obama’s administration’s use of drones. She recently wrote a book on the subject called Drone Warfare: Killing by Remote Control.
