The CIA is asking a federal judge in Washington for more time to declassify its still-secret response to a Senate intelligence report on harsh interrogation techniques and a separate review ordered by former agency director Leon Panetta.

Justice Department lawyers representing the intelligence agency asked U.S. District Court Judge James E. Boasberg on Thursday to lift a May 22 deadline in a lawsuit filed by the American Civil Liberties Union seeking the two classified reports.

Already in the process of declassifying a 500-page summary of the Senate Intelligence Committee's report on the harsh techniques, the CIA says it will need more time to similarly review the other two documents. Government lawyers say the CIA would be able to provide a timetable by June 20.
