MSNBC and other news organizations have identified the suspect as James J. Lee (pictured right.) Lee was arrested in February 2008 and has a website registered to his name called SavethePlanetProtest.com. At the time of his arrest, he was handing out a leaflet in which he raised a number of objections, namely accusing the Discovery Channel of covering only some environmental issues. He was given a suspended sentence and a restraining order was put into place. (Read more about his environmental agenda below.)
Sources say he is upset with Discovery Communications for its reports on global warming and overpopulation. He has a history of protests at the building in suburban Washington.
