The U.S. Senate Intelligence Committee asked the CIA for what the panel says it believes is a critical internal report on interrogations that has been withheld.
The committee's request comes in the midst of a yearlong battle with the U.S. spy agency over the panel's own report about the controversial detention and interrogation program, the New York Times reported Tuesday.
The Senate report of more than 6,000 pages was finished in December 2012 but hasn't been declassified.
People who read the study told the Times it is extremely critical of the defunct interrogation program and chronicles how CIA officials repeatedly mislead the White House, Congress and the public are divided on the value of brutal interrogation methods that ultimately produced intelligence of little worth.
Sen. Mark Udall, D-Colo., disclosed the existence of the CIA report during a committee hearing Tuesday, saying it was several years old and "consistent with the Intelligence's Committee's report," but conflicted with "the official CIA response to the committee's report."
