At a $5,000-a-seat fundraiser, even the heckling is well-mannered: After 21 activists from the Bradley Manning Support Network interrupted a speech by President Obama at the event at the St. Regis hotel in San Francisco, they stuck around and spoke with the president about their concerns. Some donned shirts that read "Free Bradley Manning" and broke into a song protesting Manning's treatment, singing, "Alone in a 6x12 cell sits Bradley / 23 hours a day is night / The Fifth and Eighth Amendments say this kind of thing ain't right / We paid our dues, where's our change?" Several protesters were asked to leave, but others remained. Obama later spoke with them and defended the government's handling of the case, saying the release of the documents damaged diplomatic sources. Manning, who awaits trial for the leaking of the WikiLeaks diplomatic cables, was recently moved to a prison in Fort Leavenworth, Kansas. Critics say Manning was subject to cruel and unusual punishment when he was held in solitary confinement and forced to sleep naked while being held at the Marine Corps brig in Quantico, Virginia.
