But I heard they were accusing Cheney of being involved in it when he was Defense Secretary.
Cheney allowed the evidence suppressed. So did Nixon, Carter, Reagan, Bush Sr, Clinton and GWB. Cheney was Defense Secretary when the hearings were being held, and McCain and Kerry were destroying documents. So yes, the buck did go up the chain to the Secretary of Defense, Dick Cheney. All he needs to do is explain.
