Donald Trump Goes on Anti-Cruz Tirade With 'Dirty' Campaign Charge

— -- Real estate mogul Donald Trump went on Twitter this morning and accused Texas Sen. Ted Cruz of stealing the Iowa caucuses.

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.
