A bicameral special committee is necessary, according to Chambliss, because it would allow investigators to subpoena members of the State Department. He complained the Senate Intelligence Committee, on which he is the ranking Republican, lacked that power when it probed the 2012 attack on the U.S. diplomatic annex in Benghazi.
“We were frustrated in our investigation by the lack of ability to subpoena witnesses and, particularly, subpoena documents from the State Department,” he said. “The State Department was not complicit in our investigation. They stonewalled us time and time again.”
Sen. John McCain (Ariz.), another senior Republican on Armed Services, said he would support setting up a bipartisan, bicameral special committee.
“Absolutely,” he said. “So there’s equal representation.”
McCain said it would be important to create such a panel because “the Senate has its responsibilities as well as the House.”
