Memoir to be published by Cheney tells all. It was delight that turned to contempt. "In his memoirs, Mr Cheney will make clear "doubts about the main channels of American policy during the last few years," John Hannah, his foreign policy adviser during the second Bush term, told The Post. Personal factors also contributed to the growing distance between the two men. Mr Cheney was dismayed when Mr Bush forced his old friend and mentor Donald Rumsfeld out of the Pentagon in 2006. At the time he described the departing Mr Rumsfeld as the "finest" Secretary of Defence in history â not a widely-shared view. Later, Mr Cheney was even more upset by Mr Bush's refusal when he left office to grant a pardon to the vice-president's former chief of staff Lewis "Scooter" Libby, convicted of perjury in 2007 for leaking the name of a CIA operative. After his impassioned appeals were rejected, Mr Cheney reportedly accused Mr Bush of "abandoning" an innocent man, likening it to "leaving a soldier on the battlefield.""
