South Carolina GOP Sen. Lindsey Graham says he will continue to try to block President Obama’s two nominees for high-level posts until he talks to survivors of the fatal Benghazi terror attacks.

Graham, a member of the Senate Armed Services Committee, said he hopes there’s a way to arrange interviews with five State Department employees so he can let the nominations move forward.

“All I want to do is talk to the survivors, protecting their security, protecting their identity, to find out exactly what did happen,” Graham told CNN’s “State of the Union.”

Graham said he would stall the nominations after a “60 Minutes” story in late October in which a former contractor at a British security company falsely claimed to be at the scene of the Benghazi assault.
