We spend the hour with Julian Assange, the founder of WikiLeaks, talking about the biggest leak in U.S. history: the release of more than 91,000 classified military records on the war in Afghanistan. As the Pentagon announces it is launching a criminal probe into who leaked the documents, Assange asks what about investigating the "war crimes" revealed in the leaked military records? He also talks about the media, why he isn't coming to the U.S. anytime soon and what gives him hope. "What keeps us going is our sources. These are the people, presumably, who are inside these organizations, who want change," Assange says. "They are both heroic figures taking much greater risks than I ever do, and they are pushing and showing that they want change in, in fact, an extremely effective way."
