The CIA’s internal watchdog claims it accidentally deleted its only copy of the controversial “torture report” outlining the agency’s use of enhanced interrogations techniques, the latest wrinkle in the saga over the report’s publication.

The Senate Intelligence Committee’s 6,700-page report has not yet been made public by the Obama administration and has been at the center over a years-long fight to make the report public. There are other copies of the report at other federal agencies.

Former Chair and current ranking Democrat Sen. Dianne Feinstein has been pushing for the report to be released while Republican Chairman Richard Burr has opposed even distribution of the full report to the executive branch, let alone the public.

Yahoo News first reported Monday that the CIA inspector general had “mistakenly” deleted both the electronic and hard copy of the report. Yahoo reported that officials deleted the uploaded version of the report and then accidentally destroyed a disk that contained the report.
