Despite controversy over his recent remarks, Donald Trump told Fox Business' Maria Bartiromo he won't change his temperament because he has "been winning" and it is what has gotten him to the point he is at now.

"Let me ask you about changes you've made to the campaign, Mr. Trump. Are we looking at a different mentality going into these final three months headed up to the election?" Bartiromo asked the Republican presidential nominee. "Are you changing your own temperament, changing your speeches in any way to make sure to get back where you are in the polls?"

Trump cited his Republican primary victories as reasons he has no plans to change.

Recent polls from NBC News, Suffolk University, and WBUR-FM show Trump falling behind Clinton both nationwide and in swing states like Florida and New Hampshire.

CNN's Poll of Polls, which averages six major surveys conducted between July 29 and Aug. 4, shows Clinton ahead of Trump by 10 percentage points, even when third-party candidates Gary Johnson and Jill Stein are included.

"I think my temperament has gotten me here. I've always had a good temperament, and it's gotten me here," Trump told Bartiromo, adding his campaign has "very good polling information." He didn't go into specifics on the polling data.

"I certainly don't think it's appropriate to start changing all of a sudden when you've been winning," the New York billionaire said. "I mean, I've beaten many people, and now we're down to one, and we'll see how it all works out, but I think it's going to work out well."

During a speech Monday before the Detroit Economic Club, Trump exercised restraint when interrupted by hecklers, showing he may be softening his approach after all, considering his often aggressive response to opponents in other forums.

His campaign celebrated the event in a fundraising email, saying "we stayed on message and delivered our positive platform to America," according to CNN.
