Furthermore, given the volume and internal nature of relevant CIA documents, the CIA insisted that the Committee enter into an arrangement where our staff would review documents and conduct research at a CIA-leased facility rather than at the Committee's offices on Capitol Hill.
From early 2009 to late 2012, a small group of Committee staff reviewed the more than six million pages of CIA materials, to include operational cables, intelligence reports, internal memoranda and emails, briefing materials, interview transcripts, contracts, and other records. Draft sections of the Study were prepared and distributed to the full Committee membership beginning in October 2011 and this process continued through to the Committee's vote to approve the full Committee Study on December 13, 2012.
The breadth of documentary material on which the Study relied and which the Committee Study cites is unprecedented. While the Committee did not interview CIA officials in the context of the Committee Study, it had access to and drew from the interviews of numerous CIA officials conducted by the CIA's Inspector General and the CIA Oral History program on subjects that lie at the heart of the Committee Study, as well as past testimony to the Committee.
Following the December 2012 vote, the Committee Study was sent to the President and appropriate parts of the Executive Branch for comments by February 15, 2013. The CIA responded in late June 2013 with extensive comments on the Findings and Conclusions, based in part on the responses of CIA officials involved in the program. At my direction, the Committee staff met with CIA representatives in order to fully understand the CIA's comments, and then incorporated suggested edits or comments as appropriate.
The Committee Study, including the now-declassified Executive Summary and Findings and Conclusions, as updated is now final and represents the official views of the Committee. This and future Administrations should use this Study to guide future programs, correct past mistakes, increase oversight of CIA representations to policymakers, and ensure coercive interrogation practices are not used by our government again.
Finally, I want to recognize the members of the staff who have endured years of long hours poring through the difficult details of one of the lowest points in our nation's history. They have produced the most significant and comprehensive oversight report in the Committee's history, and perhaps in that of the U.S. Senate, and their contributions should be recognized and praised.
