U.S. Republican presidential front-runner Donald Trump hammers away again at fellow candidate and rival Ted Cruz over his citizenship, questioning his closest challenger's eligibility to be U.S. president. Rough Cut (no reporter narration).
ROUGH CUT (NO REPORTER NARRATION) Republican presidential front-runner Donald Trump hammered away at fellow Republican candidate Texas Senator Ted Cruz during a campaign stop in Reno, Nevada on Sunday (January 10). Trump told a crowd of supporters that he questioned whether Cruz, who was born in Canada, is eligible to be president. Under the U.S. Constitution, presidents must be "natural born citizens." Cruz was born in Calgary, Alberta, to an American mother, which he says makes him eligible to run. Trump, who leads Republican candidates in national opinion polls, is grappling with the rise of Cruz in Iowa, which holds the first presidential nominating contest next month. As Cruz took the lead in Iowa before its Feb. 1 caucuses, Trump's glare followed. The billionaire businessman has been highlighting the citizenship issue, warning that Democrats could challenge Cruz's eligibility in court. Cruz has refused to engage with Trump on the issue. On Sunday, he said the law was straightforward. The Republican party's Senate leader said the chamber will stay out of the fray involving Ted Cruz's citizenship. Trump has said the term has not been adjudicated, and has advised Cruz to seek a judgment. The winner will face the Democrats' nominee in the November general election.
