Washington (cq-roll call) — A new revelation about a deleted copy of the Senate report on George W. Bush administration torture practices is raising concerns about the fate of the document.

Sen. Dianne Feinstein, who was chairwoman of the Intelligence Committee in December 2014 when the panel released public findings of the classified report on the Central Intelligence Agency’s use of enhanced interrogation practices, has fired off a letter to Director John Brennan seeking to provide a new copy of the report to the CIA inspector general, after a copy there was apparently misplaced or deleted.

“Your prompt response will allay my concern that this was more than an ‘accident,’ ” the California Democrat wrote on Friday. “The CIA IG should have a copy of the full study because the report includes extensive information directly related to the IG’s ongoing oversight of the CIA.”

The IG’s office has said it unintentionally deleted the computer file.
