WASHINGTON (AP) — A House committee chairman issued two subpoenas Thursday to the State Department for documents related to the deadly assault last year on the U.S. diplomatic mission in Benghazi, Libya.

Rep. Darrell Issa, R-Calif., said he wanted all documents the department gave to an independent review board headed by former diplomat Thomas Pickering and retired Adm. Mike Mullen. Issa, who chairs the House Oversight and Government Reform Committee, also asked for all documents and communications related to interviews conducted by the board.
