Rice, Cheney approved waterboarding
Updated on 23 April 2009
It is emerging that practices like waterboarding were sanctioned at the highest level of the Bush administration.
It began with secret memos revealing the CIA's brutal treatment of terror suspects. Now the political storm has spread to who knew what, and when.
Senior officials, including Condoleezza Rice and former vice-president Dick Cheney were fully briefed by the CIA on their interrogation methods and gave their seal of approval.
That has prompted calls for a new truth commission to investigate whether anyone should be prosecuted.
