The Senate's forthcoming report on the CIA's use of harsh interrogation techniques could add to the legal complications facing the long-delayed U.S. military tribunals of terrorist suspects at the Guantanamo Bay detention camp.

The Obama administration is declassifying the report, a process that will involve the Pentagon as well as CIA officials. Two U.S. officials familiar with planning for the report's declassification said the Defense Department has already received copies of the still-secret summary of the Senate Intelligence Committee's report and expects to provide its own assessment of the material to the administration.

The officials spoke anonymously about the report because they were not authorized to discuss publicly the declassification review.

Legal experts say the report could alter tactics in both the military trials and in federal courts.
