Donald Trump Threatens to 'Spill the Beans' on Cruz's Wife After Racy Photo of Melania Trump Used in Ad

Trump took aim at Cruz after racy photo of Melania used in ad.

The digital ad has been running in Utah and Arizona for the last several days, according to the group. The ad targets the conservative voting bloc of female Mormon voters and ran along with two other anti-Trump ads targeting both male and female Mormon voters.

Trump's campaign has not responded to requests for comment about what the candidate was referring to.

In a tweet, Ted Cruz, said that the ad had nothing to do with him.
