Trump criticized the Texas senator for spreading rumors that neurosurgeon Ben Carson was dropping out of the Iowa caucuses. A day after winning the Iowa caucuses, Cruz Tuesday issued an apology to Carson after his staff falsely told Iowa caucusgoers that Carson planned to quit the race, calling it a "mistake."

Trump is doing more than just going after Cruz on Twitter; he's doing it in his campaign speeches and at his news conferences. When ABC News asked Trump at a news conference Tuesday night whether Cruz is running a dirty campaign, he said, "I think he was certainly dirty. What he did to Ben Carson was terrible. I think what he did to voter violation forum; I thought that was terrible."

Trump campaign manager Corey Lewandowski says the GOP presidential candidate “speaks for himself” in his tweets.
