Donald Trump on Tuesday threatened to “spill the beans” on Sen. Ted Cruz’s wife, Heidi Cruz.
In a brazen new tweet, Trump criticised Cruz over a television advertisement that an unaffiliated, anti-Trump super PAC ran in the lead-up to Utah’s caucuses Tuesday.
The ad showed Trump’s wife, Melania Trump, posing nude in a GQ magazine photoshoot.
“Lyin’ Ted Cruz just used a picture of Melania from a G.Q. shoot in his ad. Be careful, Lyin’ Ted, or I will spill the beans on your wife!” Trump tweeted.
Cruz responded shortly after. In his own tweet, the senator pointed out that his team was not responsible for the ad, and slammed Trump for considering attacking Heidi Cruz.
Trump’s wild Twitter tactics have partially redefined the GOP primary. Trump often lashes out at his rivals in a mixture of belittlement and aggression. The frontrunner’s Tuesday-night threat against Cruz’s wife is an especially remarkable statement as he seeks to unify the GOP rank-and-file behind his campaign.
The Trump and Cruz campaigns did not immediately respond to requests for comment from Business Insider. The two GOP rivals are squaring off in contests in Utah and Arizona on Tuesday night.
