Witnesses in the trial of a U.S. soldier charged with abusing prisoners at Abu Ghraib have told the court that the CIA sometimes directed abuse and orders were received from military command to toughen interrogations. The evidence, from an officer and a chief warrant officer who served at the jail, is among the strongest so far in the Abu Ghraib trials pointing to more senior involvement in the abuse and direct orders from above to "soften up" detainees.
