Rand Paul: Ted Cruz's eligibility could reach SCOTUS

“The thing is, all experts agree that he was naturally born in Canada,” Paul said on CBS’s “Face the Nation.” “And so the question is — can you be naturally born in Canada and also be considered to be a natural born citizen? It hasn’t been decided.”

“[The Founding Fathers] used this unusual language in the Constitution of ‘natural born’, and so I think it will be brought up,” the Kentucky Republican continued. “Congressman [Alan] Grayson from Florida is already saying he’s going to challenge it in court. I think the Democrats will challenge it at the very least and I think it will have to be decided by the Supreme Court.”

Cruz, the GOP front-runner in Iowa, was born in Canada to an American mother and Cuban father.
