White House responds to Senate's Benghazi inquiry: 'Take a hike.

That's the message Sen. Lindsey Graham says he received in response to a letter requesting access to Benghazi witnesses.

Graham appeared Tuesday morning on Fox News and explained that the quest for answers about the September 11, 2012 terrorist attack in Libya and the administration's immediate response.

"I’m trying to find out did the people on the ground during the attack ever say it was a protest? Did they ask for security weeks or months before the attack and who turned them down?" the South Carolina Republican said. "How can I go to the families and tell them that I know the story of Benghazi when we can’t talk to the survivors?"

Without answers, Graham warned, the Senate could stall the president's nominees to fill currently vacant positions.
