Republican presidential candidate Donald Trump is threatening to file a lawsuit against rival Ted Cruz challenging his eligibility to serve in the White House unless the Texas senator stops airing what Trump’s campaign calls "false ads" and retract what it calls "his lies."
Trump lashed out Monday in the lead-up to this weekend’s South Carolina primary, taking specific aim at Cruz. At events and in a press release, Trump calls Cruz "the most dishonest guy I think I’ve ever met in politics."
The billionaire real estate mogul has previously said a federal court should decide whether Cruz meets the Constitutional requirement of being a "natural born citizen" to serve as president.
Cruz was born in Canada to an American mother, and legal experts have said he meets that test.
