Former Vice President Dick Cheney has criticized George W. Bush’s decision not to pardon Cheney’s former chief of staff, Lewis “Scooter” Libby. Bush commuted Libby’s sentence for his role in the leak of CIA agent Valerie Plame’s identity but didn’t grant a full pardon. Speaking to his biographer, Cheney said, “[Libby] was the victim of a serious miscarriage of justice, and I strongly believe that he deserved a presidential pardon. Obviously, I disagree with President Bush’s decision.”
