Per a statement from Attorney General Eric Holder:

"The Office of Professional Responsibility has now submitted to me its report regarding the Office of Legal Counsel memoranda related to so-called enhanced interrogation techniques.  I hope to be able to make as much of that report available as possible after it undergoes a declassification review and other steps.  Among other findings, the report recommends that the Department reexamine previous decisions to decline prosecution in several cases related to the interrogation of certain detainees.

"I have reviewed the OPR report in depth.  Moreover, I have closely examined the full, still-classified version of the 2004 CIA Inspector General's report, as well as other relevant information available to the Department.  As a result of my analysis of all of this material, I have concluded that the information known to me warrants opening a preliminary review into whether federal laws were violated in connection with the interrogation of specific detainees at overseas locations.  The Department regularly uses preliminary reviews to gather information to determine whether there is sufficient predication to warrant a full investigation of a matter.  I want to emphasize that neither the opening of a preliminary review nor, if evidence warrants it, the commencement of a full investigation, means that charges will necessarily follow.

"Assistant United States Attorney John Durham was appointed in 2008 by then-Attorney General Michael Mukasey to investigate the destruction of CIA videotapes of detainee interrogations.  During the course of that investigation, Mr. Durham has gained great familiarity with much of the information that is relevant to the matter at hand.  Accordingly, I have decided to expand his mandate to encompass this related review.  Mr. Durham, who is a career prosecutor with the Department of Justice and who has assembled a strong investigative team of experienced professionals, will recommend to me whether there is sufficient predication for a full investigation into whether the law was violated in connection with the interrogation of certain detainees."
