In Seneca, S.C., on Wednesday, the Texas senator showed an ad that featured Trump being interviewed on MSNBC more than a decade ago, in which he said he was pro-choice. The ad condemns Trump's "New York values."
"Donald, if you want to file a lawsuit challenging this ad, claiming it's defamation, file the lawsuit," Cruz told reporters.
Days ago, Trump threatened to sue Cruz "relative to the fact that he was born in Canada and therefore cannot be president," a claim Trump has pushed harder since the fight between the two candidates has grown more bitter in recent weeks, "if [Cruz] doesn't take down his false ads and retract his lies."
"One of the things I look forward to most of all is deposing Donald Trump," Cruz said. "And for that particular endeavor I may not use outside counsel. I may take the deposition myself. And I will say this: Whether in a deposition or in a court of law, getting Donald Trump under oath, under penalty of perjury, answering these questions? Well I'll point out, it didn't work out very well for Bill Clinton. Donald Trump does not want to be under oath answering questions about his own record."
Cruz, a Harvard-educated lawyer and former Texas solicitor general, warned that Trump and his lawyers would be "sanctioned in court for filing frivolous litigation."
