Sen. Lindsey Graham said Monday that he will block “every appointment” in the Senate from President Obama until the administration makes available the survivors of the Benghazi, Libya attack for questioning.

“Where are the Benghazi survivors? I'm going to block every appointment in the US Senate until they are made available to Congress,” the South Carolina Republican tweeted after also calling for a joint congressional committee to probe the killings that occurred while Hillary Clinton was secretary of State.

He repeated his tweets on Fox, adding, “We’re just beginning on Benghazi.”
