The Supreme Court has turned away an appeal seeking to force the CIA to release the full 2014 Senate report about the agency's use of harsh interrogation tactics.

The justices on Monday let stand an appeals court ruling that said the 6,900-page report prepared by the Senate Intelligence Committee was not subject to Freedom of Information laws.

The committee previously released a lengthy summary of the report to the public, but the American Civil Liberties Union sued to obtain the full version. The ACLU argued that the report became subject to disclosure laws after the committee sent it around to several federal agencies for review.

The appeals court said Congress clearly intended to retain control of the report.
