Senator Ted Cruz (R-TX) announced on Monday evening that he will renounce his Canadian citizenship. The news broke after some questioned whether the Canadian-born senator was eligible to be president of the United States.

Sen. Cruz Blasts the President: 'Obama Is NOT Following the Constitution'

The Tea Party favorite released his birth certificate in response, but The Dallas Morning News pointed out that even though he was born to an American mother, “under Canadian law, he also became a citizen of that country the moment he was born.”

The Constitution says only a natural born citizen is eligible to be president, but critics point out that it does not address dual citizenship. Tonight on Hannity, former Florida Congressman Connie Mack and Democratic strategist Steve Murphy debated the issue.

Hannity asked Murphy if he’s a “left-wing birther,” playing on the birther movement that came up during President Obama’s first term. Murphy thinks Cruz is eligible to run because he’s a U.S. citizen, but added this dig: “His problem isn’t he’s from Canada, it’s he’s from Mars.”

The Fox News host said the left is “flirting with birtherism” and took it a step further, asking, “Does that mean that they’re racist against a Hispanic?”

Mack said this was “clearly a media dump,” alleging that one of Cruz’s political opponents stirred up the controversy because they saw him as a threat. “He’s a conservative and that drives others crazy.”
