Did he apologize or not ?
It wasn't for his staff to repeat Carson's announcement, or the CNN headline. Cruz openly said, "What the team then should have done was send around the follow-up statement from the Carson campaign clarifying that he was indeed staying in the race when that came out."
But again, nobody can find the words "dropping out" anywhere... not from Carson, not from CNN, not from Rubio's people (who were also broadcasting the news as it hit), and not from Cruz's people... but somehow, only Cruz's people are to blame. Hmm.
