A bipartisan Senate report released today says that former Defense Secretary Donald Rumsfeld and other top Bush administration officials are directly responsible for abuses of detainees at Guantanamo Bay, Cuba, and charges that decisions by those officials led to serious offenses against prisoners in Iraq and elsewhere.

The Senate Armed Services Committee report accuses Rumsfeld and his deputies of being the principal architects of the plan to use harsh interrogation techniques on captured fighters and terrorism suspects, rejecting the Bush administration's contention that the policies originated lower down the command chain.
