WATCH: Donald Trump and Ted Cruz Jab at Republican Debate Over Birther Question

Donald Trump and Ted Cruz had a back-and-forth moment for the ages on Thursday night at the Republican Presidential Candidates Debate. The debate between the two Republican candidates began when Ted Cruz was asked about his status as a natural-born United States citizen. Cruz was born in Calgary, Canada to an American-born mother. That hasn’t stopped Trump, who also fueled the theory that Barack Obama was born in Kenya, from casting doubt on Cruz’s qualification for the highest office in the land.

Cruz defended himself by countering that his ineligibility would also likely result in other candidates including Trump, whose mother was born in Scotland, being ineligible for Presidential office.

Trump responded by calling upon his superior poll numbers.

“In Iowa, in the last the polls as you know Ted, I am beating you,” Trump declared. “You shouldn’t misrepresent how well you’re doing in the polls… I don’t care, I think I’m going to win fair and square.”

Trump then went on to say that the difference in their qualifications for the office of President lies in the birthplace of he compared to the birthplace of Cruz. Trump was born in Queens, New York.

“There’s a big question mark on your head, and you can’t do that to the party,” Trump continued.

Donald Trump does now hold a double-digit lead over Republican opponent Sen. Ted Cruz, according to the latest Wall Street Journal/NBC News poll. The poll shows that Trump is the choice of 33 percent of Republican primary voters.

Fox Business hosts Neil Cavuto and Maria Bartiromo were the moderators for tonight’s GOP Debate from the North Charleston Coliseum and Performing Arts Center in North Charleston, SC.
