Rep. Issa Subpoenas Four State Department Officials

Part of investigation into attack on American consulate in Benghazi

House Oversight Chairman Darrell Issa (R-Calif.) on Tuesday subpoenaed four State Department officials as part of his investigation into the administration's response to the Benghazi mission attack.

In a sharply worded letter to Secretary of State John Kerry, Issa wrote that State chief of staff David Wade has been uncooperative since being first approached in mid-May with the request to make 13 State Department personnel available for depositions.

"I am concerned that waiting weeks or months while the Department prepares witnesses to be interviewed creates the risk that their testimony will have been rehearsed or coached," Issa wrote. "The Department has left me with no alternative but to issue subpoenas to compel testimony from these important witnesses."
