House Oversight Committee Chairman Darrell Issa on Tuesday accused the Obama administration of “withholding information” about the Benghazi terror attack. The California Republican has subpoenaed more documents related to the talking points on the Sept. 11, 2012 attack on the U.S. Consulate that left four Americans dead.

In a subpoena sent Tuesday, Issa requested “all documents and communications referring or relating to the Benghazi talking points” sent to or from a list of ten current and former State Department officials.

“The State Department has not lived up to the Administration’s broad and unambiguous promises of cooperation with Congress,” Issa said in a letter sent Tuesday to Kerry. “Therefore, I am left with no alternative but to compel the State Department to produce relevant documents through a subpoena.”
