■ He denied that he has any business dealings in Russia: “I tweeted out that I have no dealings with Russia. I have no deals in Russia. I have no deals that could happen in Russia because we’ve stayed away. And I have no loans with Russia. As a real estate developer, I have very, very little debt.”

■ Mr. Trump said he had requested that the intelligence agencies produce a “major report” on “hacking defense” to be delivered 90 days after he takes office, including an examination of “this situation” with Russia and other incidents of hacking.

Details on his business plans

■ Sheri A. Dillon, a lawyer for Mr. Trump, took the stage to describe how her client would turn over his business assets to a trust. “President-elect Trump wants there to be no doubt in the minds of the American public that he is completely isolating himself from his business interests,” she said, adding that Mr. Trump’s sons will make all decisions for the company “without any involvement whatsoever” from Mr. Trump. She said Mr. Trump would resign from all positions he holds with the Trump Organization, as would his daughter Ivanka.

■ Ms. Dillon said that the Trump Organization would be allowed to make no new foreign deals during the presidency and that any new domestic deals would be subject to strict restrictions. “He will only know of a deal if he reads about it in the paper or sees it on TV,” Ms. Dillon said, referring to Mr. Trump. She also said an ethics adviser would be appointed to the management team of the Trump Organization.

■ Ms. Dillon argued that selling Mr. Trump’s business would prove more difficult and create more ethical quandaries than the plan that the Trump Organization had chosen. A totally blind trust, she said, would likewise be impossible under the circumstances. And, she added, “President-elect Trump should not be expected to destroy the company he built.”

■ Ms. Dillon laid out what amounts to the Trump administration’s interpretation of the Constitution’s Emoluments Clause, which prohibits government officials from taking payments or gifts from a foreign government. “No one would have thought when the Constitution was written, that paying your hotel bill was an emolument,” she said. To avoid any appearances of violations, Ms. Dillon said Mr. Trump had pledged to donate to the United States government all profits made by his hotels from payments by foreign governments.

■ Mr. Trump was flanked by a table piled high with manila folders that he said contained paperwork that he had signed turning over control of the Trump Organization to his sons.
