CHARLOTTE, N.C. (AP) — In a highly uncharacteristic move aimed at resetting his struggling campaign, Donald Trump says for the first time he regrets some of the caustic comments he's made that may have caused people pain.

Trump told a rally in Charlotte, North Carolina, Thursday night: "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. I have done that." He added: "And believe it or not, I regret it — and I do regret it — particularly where it may have caused personal pain."

It was a rare admission for Trump, who has said he prefers "not to regret anything." It underscored the dire situation he finds himself in with just 80 days left until the election.
