From National Security Archive:
The State Department today released a February 2006 internal memo from the Department's then-counselor opposing Justice Department authorization for "enhanced interrogation techniques" by the CIA. All copies of the memo (Document 1), which reflect strong internal disagreement within the George W. Bush administration over the constitutionality of such techniques, were thought to have been destroyed. But the State Department located a copy and declassified it in response to a Freedom of Information Act request by the National Security Archive.
