"Sometimes in the heat of debate and speaking on a multitude of issues, you don't choose the right words or you say the wrong thing," Trump told a rally in Charlotte, North Carolina. "I have done that. And believe it or not, I regret it," he said, drawing laughs and applause from the crowd. "I do regret it. Particularly, where it may have caused personal pain."
He added: "Too much is at stake for us to be consumed with these issues, but one thing, I can promise you this, I will always tell you the truth."
