Same lawyers who said anchor babies are in the Constitution now tell us being born outside U.S to 1 American parent = natural born citizen. — Ann Coulter (@AnnCoulter) January 6, 2016

NYT: Cruz was born outside the U.S. to 1 American parent: "Under the Constitution this makes him a 'natural born citizen.'” Absolutely false — Ann Coulter (@AnnCoulter) January 6, 2016

Coulter joins Trump in questioning whether Cruz can legally be president.



“Republicans are going to have to ask themselves the question: ‘Do we want a candidate who could be tied up in court for two years?’ That’d be a big problem,” Trump told The Washington Post on Tuesday.



The U.S. Constitution states that to be eligible for the White House, one must be a “natural born citizen.” That’s long been interpreted to include anyone born to a U.S. citizen, even outside the country.



Cruz was born in Canada to an American mother and Cuban father. For years he held dual U.S.-Canada citizenship. The Texas Republican renounced his Canadian citizenship after he became a U.S. senator.



Cruz has laughed off the suggestion he’s not eligible for the White House, taking to Twitter on Tuesday to post a link from the television show “Happy Days” that shows the character Fonzie on water skis jumping over a shark.

Cruz and Trump are battling atop the polls in Iowa with less than a month to go before the caucuses there.
