Speaking at a breakfast Thursday morning with the Texas delegation at the RNC, Cruz said Trump’s negative comments about Cruz’s wife and father kept him from endorsing the real estate mogul for president. “You might have a similar view, if someone were attacking your wife,” Cruz told an audience member. He argued that the pledge made during the GOP primary, in which he and other GOP hopefuls said they would vote for the eventual Republican nominee, was “not a blanket commitment.” “[I’m not going to] come like a servile puppy dog and say, ‘thank you very much for maligning my wife and maligning my father,’” Cruz added, promising he would not vote for presumptive Democratic presidential nominee Hillary Clinton.
