President George W. Bush has demoted Army Reserve Brig. Gen. Janis Karpinski, who was in charge of Abu Ghraib during the prison abuse scandal in 2003, after an extensive investigation, the Pentagon said Thursday. Now a colonel, Karpinski was formally relieved of command of the 800th military police brigade last month, according to a report of CNN. She is the only high-level officer to be disciplined so far in a scandal that provoked outrage and headlines around the world.
