(Mic.com) -- President Barack Obama can put away his birth certificate for a while: Republican frontrunner and habitual pot-stirrer Donald Trump has found a new U.S. citizen to hassle. Trump has failed to overtake Texan Sen. Ted Cruz in Iowa primary polls. His strategy for winning the critical state? To call into question Cruz's citizenship, the New York Times reported. Cruz was born in Canada; because his mother is U.S.-born, Cruz holds dual citizenship. But as Trump alleges, Cruz's Canadian origin could land the candidate in a world of legal trouble, proving a roadblock in his bid for the White House.
"I'd hate to see something like that get in his way," Trump said, according to the Washington Post. "But a lot of people are talking about it and I know that even some states are looking at it very strongly, the fact that he was born in Canada and he has had a double passport."
