Donald Trump on Republican debate: I could tone it down

To the critics who think Donald Trump's fiery rhetoric could be toned down, it turns out, the real estate mogul agrees with you.<br />"I think I could tone it down a little bit when pressed," Trump told the Christian Broadcasting Network's David Brody, in an interview published Wednesday.<br />"I've had a great temperament.<br />You couldn't build a great business like I've built if you didn't have good temperament but I think maybe I can sometimes tone it down.<br />When somebody hits, you can hit a little less hard.<br />At the same time that may be the kind of thing the country needs because we have to hit back hard to fight hard because we're not going to have a country."<br />Pundits have criticized Trump for his words and tone about undocumented immigrants, women and his opponents.<br />Trump also defended his tone, saying that harsh words are sometimes necessary.
