That is a blatant lie. Cruz had absolutely nothing to do with that add and has publically said that he had nothing to do with it. The add was put out by an anti Trump PAC that has absolutely no affiliation with the Cruz Campaign. Additionally Sen. Cruz is prohibited by law with coordinating with any PAC on adds.
Leaving aside the merits/demerits of this matter, I consider Mizz Kelly a noisy and pretentious nobody who is forever injecting herself into matters that are none of her business.
