“I can’t discuss the possibility of the U.S. involvement in Syria’s civil war without also talking about Benghazi,” Rep. Jeff Duncan (R-S.C.) told Secretary of State John Kerry during a testy exchange at Wednesday’s House Foreign Affairs hearing.

“The administration has a serious credibility issue with the American people due to the unanswered questions surrounding the terrorist attack in Benghazi almost a year ago,” Duncan said.

Duncan’s line of questioning drew the angriest response of the hours-long hearing.

“We’re talking about people being killed by gas and you want to go talk about Benghazi and Fast and Furious,” Kerry replied. “We don’t deserve to drag this into yet another Benghazi discussion when the real issue here is whether or not the Congress is going to stand up for international norms.”
