SPOKANE, Wash. (AP) — Two former Air Force psychologists from Washington state who helped design the CIA's enhanced interrogation techniques for terrorism suspects are denying a group's allegations of torture and war crimes.

But James E. Mitchell and John "Bruce" Jessen acknowledge in new court documents that they used waterboarding, loud music, confinement, slapping and other harsh tactics.

The American Civil Liberties Union sued the pair last October on behalf of three former CIA prisoners, creating a closely watched case that will likely include secret information.

Lawyers for the psychologists filed documents in federal court refuting that the techniques were torture.

Mitchell and Jessen declined to respond to many of the ACLU's allegations, saying much of the information is classified.

The group also has sued the CIA and its former director George Tenet.
