NEW YORK — President-elect Donald Trump tempered some of his most extreme campaign promises Tuesday, dropping his vow to jail Hillary Clinton, expressing doubt about the value of torturing terrorism suspects, and pledging to have an open mind about climate change.

But in a wide-ranging, hourlong interview with reporters and editors at The New York Times — which was scheduled, canceled, and then reinstated after a dispute over the ground rules — Trump was unapologetic about flouting some of the traditional ethical and political conventions that have long shaped the American presidency.

He said he had no legal obligation to establish boundaries between his business empire and his White House, conceding that the Trump brand “is certainly a hotter brand than it was before.’’ Still, he said he would try to figure out a way to insulate himself from his businesses, which would be run by his children.

He defended Stephen Bannon, his chief strategist, against charges of racism, calling him a “decent guy.’’ And he mocked Republicans who had failed to support him in his unorthodox presidential campaign.

In the midday meeting in the 16th-floor boardroom of The Times’ publisher, Arthur Sulzberger Jr., Trump seemed confident even as he said he was awed by his new job.

“It is a very overwhelming job, but I’m not overwhelmed by it,’’ he said.

Trump, who left late Tuesday to spend Thanksgiving at his estate in Florida, also continued to work to populate his incoming administration.

The Associated Press reported that he had officially asked GOP presidential rival Ben Carson to head the Department of Housing and Urban Development, according to a person familiar with the offer who spoke on the condition of anonymity because the person was not authorized to discuss the deliberations publicly.

Carson is expected to respond after the holiday.

In the Times interview, Trump displayed a jumble of impulses, many of them conflicting. He was magnanimous toward Clinton, but boastful about his victory. He was open-minded about some of his positions, uncompromising about others.

The interview demonstrated the volatility in Trump’s positions.

He said he had no interest in pressing for Clinton’s prosecution over her use of a private ­e-mail server or for financial acts committed by the Clinton Foundation.

“I don’t want to hurt the Clintons, I really don’t,’’ he said.

On the issue of torture, Trump suggested he had changed his mind about the usefulness of waterboarding after talking with James N. Mattis, a retired Marine Corps general, who headed US Central Command.

“He said, ‘I’ve never found it to be useful,’ ’’ Trump said. He added that Mattis found more value in building trust and rewarding cooperation with terrorism suspects: “ ‘Give me a pack of cigarettes and a couple of beers, and I’ll do better.’ ’’

“I was very impressed by that answer,’’ Trump said.

Torture, he said, is “not going to make the kind of a difference that a lot of people are thinking.’’

Trump repeated that Mattis was being “seriously, seriously considered’’ to be secretary of defense.

“I think it’s time, maybe, for a general,’’ he said.

On climate change, Trump refused to repeat his promise to abandon the international climate accord reached last year in Paris, saying “I’m looking at it very closely.’’

Despite the recent appointment to his transition team of a fierce critic of the Paris accords, Trump said that “I have an open mind to it’’ and that clean air and “crystal clear water’’ were vitally important.

He held out assurances that he did not intend to embrace extremist positions in some areas. He denounced a white nationalist conference last weekend in Washington, where attendees gave the Nazi salute and criticized Jews.

Pressed to respond to criticism in other areas, he was defiant. He declared that “the law’s totally on my side’’ when it comes to questions about conflict of interest and ethics laws.

“The president can’t have a conflict of interest,’’ he said.

He said it would be extremely difficult to sell off his businesses because they are real estate holdings. He said that he would “like to do something’’ and create some kind of arrangement to separate his businesses from his work in government.

He noted that he had turned over the management of his businesses to his children, which ethics lawyers say is not sufficient to prevent conflicts of interest.

He insisted that he could still invite business partners into the White House for grip-and-grin photographs. He said that critics were pressuring him to go beyond what he was willing to do, including distancing himself from his children while they run his businesses.

“If it were up to some people,’’ he said, “I would never, ever see my daughter Ivanka again.’’

Trump rejected the idea that he was bound by federal anti-nepotism laws against installing his son-in-law, Jared Kushner, in a White House job. But he said he would want to avoid the appearance of a conflict and might instead seek to make Kushner a special envoy charged with brokering peace in the Middle East.

“The president of the United States is allowed to have whatever conflicts he or she wants, but I don’t want to do that,’’ Trump said.

But he said that Kushner, who is an observant Jew, “could be very helpful’’ in reconciling the longstanding dispute between the Israelis and the Palestinians.

“I would love to be able to be the one that made peace with Israel and the Palestinians,’’ Trump said, adding that Kushner “would be very good at it’’ and that “he knows the region.’’

Trump made a forceful defense of Bannon, whom he named as his chief strategist and who has drawn charges of racism and anti-Semitism.

This summer, Bannon called Breitbart News, the website he led, “the platform for the alt-right,’’ a white nationalist movement.

Trump said Bannon had been dismayed at the reaction to his hiring.

“I’ve known Steve Bannon a long time. If I thought he was a racist or alt-right,’’ he said, “I wouldn’t even think about hiring him.’’

And Trump gloated about defying the polls and the expectations of his own party to win the presidency, and boasted of how he had taken his revenge on Republicans who kept him at a distance and then lost their own races.

He said that one of them, Senator Kelly Ayotte of New Hampshire, would “love to have a job in the administration.’’

“I said, ‘No, thank you,’ ’’ Trump said of Ayotte, who lost her Senate seat to Governor Maggie Hassan of New Hampshire. “She refused to vote for me.’’
