And that energy reaffirmed his desire to speak more. Now reporters are finding themselves on the receiving end of late-night phone calls and impromptu Oval Office interviews, and the White House is on the receiving end of a deluge of interview requests.

Aside from taking requests from Fox News — he is already scheduling interviews into next week, including one with Fox Business on Tuesday — requests from the legacy media, such as “60 Minutes,” hold a particular allure for a president who has boasted to allies that he can’t believe how frequently he has been on the front page of The New York Times since he became president.

When he does not appear on the front page of his favorite papers, two former aides said, he has made it a point to do or say something to get there the next day.

Is presidential overload possible? At least one former White House press secretary doesn’t think so.

“Every reporter should be celebrating,” said Ari Fleischer, President George W. Bush’s press secretary. “And it will be a good strategy until something comes up from which the president will likely hide.”

Others see Mr. Trump headed toward treacherous territory as he repeatedly speaks off the cuff. When asked about the fate of Jamal Khashoggi, a Saudi columnist for The Washington Post who is believed to have been murdered, Mr. Trump seemed less concerned about Mr. Khashoggi’s disappearance than he did about the idea of losing money from the Saudis should a lucrative arms deal fall through.
