WASHINGTON (Associated Press) -- A Navy captain was demoted because she berated and assaulted her crew, not because she led her guided missile cruiser on a drag-race with another U.S. warship in the Pacific, an investigation shows. Capt. Holly Graf was relieved of her command of the cruiser USS Cowpens after an investigation substantiated crew allegations that she was abusive and used her position for personal gain, naval officials said Thursday on condition of anonymity because they were not authorized to speak on the record.
