Sen. Rand Paul (R-Ky.) suggested Tuesday that Hillary Clinton's response to the terrorist attack that killed four Americans in Benghazi, Libya, should disqualify her from serving as commander in chief.

While Paul didn't name the former secretary of state by name, he said he suspected the decision not to dispatch a rescue effort to the diplomatic outpost in Benghazi was made by "a politician," because the military would never allow something like that to happen without sending troops.

"If you've ever known somebody who's involved with the Marines, Army or otherwise, they go after and rescue their dead, their wounded," Paul said in a speech at the Citadel in South Carolina. "There were still people alive and fighting for hours upon hours, and there were some people in Tripoli who could have gone.

"I don't think that decision was made by a military person. I think it was made ultimately by a politician."

Paul said Congress needs to get answers on who made that call, and that whoever it was should never be in charge again.

"To my mind, you should never have a commander in chief who is unwilling to send in troops for reinforcement -- or in the six-month period of time, did not send adequate security when it was asked for repeatedly," Paul said in a more direct allusion to Clinton. "To me, that should preclude you from ever holding high office."
