That panel, led by former Secret Service Director Mark Sullivan, warned that the State Department did not pay enough attention to the bureau overseeing security for 275 diplomatic posts and called for it to be elevated in its importance to deal with a growing threat.
As a result of the Benghazi attack, the State Department created a new position of deputy assistant secretary of state for high threat posts and has begun to beef up security and improve training.
But Issa contended Thursday that it was the purview of his committee and that of Congress to interview many of the same witnesses who were on the ground in Benghazi that spoke to the review board in order to get an understanding of where accountability for the attack lay.
"I am in the process of issuing subpoenas because the State Department has not made those people available, has played hide and go seek, and is now hiding behind a thinly veiled statement that there's a criminal investigation," he said of the FBI probe.
And in the next sentence, Mr. Issa laid out the roadmap for his committee in the Benghazi investigation.
"That's part of the reason that this investigation cannot end until the State Department gives us at least the same access that they gave your board," he said.
