Watch: Trump Hammers Cruz on Eligibility

On Sunday at a campaign event in Ottumwa, IA, Republican presidential front-runner Donald Trump questioned Sen. Ted Cruz (R-TX) and his eligibility to be president of the United States.

“So the question is — is Ted Cruz, is he a natural born citizen?” Trump said.

According to Trump, there is some question as to whether or not his place of birth, which is Canada, makes him eligible to be president as set forth by the U.S. Constitution.

“If he were lucky enough to win, which I don’t think he’s going to — but if he were lucky enough to win and he’s your candidate, he’s going to be sued by the Democrats. They’ve already said they’re going to be suing him on the definition — and it’s right here, on the definition — is he natural-born? And a lot of people think that means you have to be born on the land, not in Canada. And so, Professor Laurence Tribe — he says you got  a lot of problems there. Let’s see what happens. But there is an out. We can’t have a doubt. We can win this election. We can win it fast.”

Trump insisted Cruz seek a “declaratory judgment” declaring whether or not he is eligible to be president.

“And I say this as a friend of the party, and as a friend of Ted — he’s got to go in and get a declaratory judgment — he’s got to get a ruling to determine if he wins, can he run? Is he allowed to run? Is he allowed to serve? Does that make sense to anybody?”
