Peace Mom" Cindy Sheehan's was arrested at Tuesday night's State of the Union address after she refused to yield to warnings from Capitol Hill police to cover up an anti-war T-shirt she was wearing underneath her coat. Capitol Police Sgt. Kimberly Schneider told the Associated Press that Sheehan kept the anti-war slogan covered until she took her seat. When they noticed her politically charged attire, police warned Sheehan that such displays were not allowed. The celebrated anti-war protester ignored the warnings, police said. Police handcuffed Sheehan and escorted her from the gallery about 15 minutes before the president arrived.
