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!— Donald J. Trump (@realDonaldTrump) March 23, 2016
In his response, Cruz said, "Pic of your wife not from us."
Liz Mair, who runs the super-PAC, went on a Twitter blitz after the exchange, pointing out that Cruz wasn't behind the ad and speculating what Trump could have been referencing.

It's possible that Trump is talking about a reported incident in 2005, when Heidi Cruz went through a period of depression and was picked up by police on the side of the road, according to BuzzFeed.
“About a decade ago, when Mrs. Cruz returned from D.C. to Texas and faced a significant professional transition, she experienced a brief bout of depression,” Jason Miller, an adviser to Cruz, told BuzzFeed.
Trump and Cruz faced off Tuesday night in contests in Arizona and Utah.
