During the campaign, when President Trump’s advisers wanted him to stop talking about a certain issue — such as when he attacked a Gold Star military family — they sometimes presented him with polls demonstrating how the controversy was harming his candidacy.
During the transition, when aides needed Trump to decide on a looming issue or appointment, they often limited him to a shortlist of two or three options and urged him to choose one.
And now in the White House, when advisers hope to prevent Trump from making what they think is an unwise decision, they frequently try to delay his final verdict — hoping he may reconsider after having time to calm down.
When Sen. Bob Corker (R-Tenn.) described the White House as “an adult day-care center” on Twitter last week, he gave voice to a certain Trumpian truth: The president is often impulsive, mercurial and difficult to manage, leading those around him to find creative ways to channel his energies.
Some Trump aides spend a significant part of their time devising ways to rein in and control the impetuous president, angling to avoid outbursts that might work against him, according to interviews with 18 aides, confidants and outside advisers, most of whom insisted on anonymity to speak candidly.

“If you visit the White House today, you see aides running around with red faces, shuffling paper and trying to keep up with this president,” said one Republican in frequent contact with the administration. “That’s what the scene is.”
The White House dismissed Corker’s suggestion that administration officials spend their days trying to contain the president. The point was highlighted last week in an unusual briefing by White House Chief of Staff John F. Kelly, who sought to tamp down reports that he was focused on attempting to control Trump.
“I was not brought to this job to control anything but the flow of information to our president so that he can make the best decisions,” Kelly told reporters. “So, again, I was not sent in to — or brought in to — control him.”

Kelly also praised Trump as “a decisive guy” and “a very thoughtful man” whose sole focus is on advancing American interests. “He takes information in from every avenue he can receive it,” Kelly said. “I restrict no one, by the way, from going in to see him. But when we go in to see him now, rather than onesies and twosies, we go in and help him collectively understand what he needs to understand to make these vital decisions.”
Trump is hardly the first president whose aides have arranged themselves around him and his management style — part of a natural effort, one senior White House official said, to help ensure the president’s success. But Trump’s penchant for Twitter feuds, name-calling and temperamental outbursts presents a unique challenge.
One defining feature of managing Trump is frequent praise, which can leave his team in what seems to be a state of perpetual compliments. The White House pushes out news releases overflowing with top officials heaping flattery on Trump; in one particularly memorable Cabinet meeting this year, each member went around the room lavishing the president with accolades.

Senior administration officials call this speaking to an “audience of one.”
One regular practitioner is Treasury Secretary Steven Mnuchin, who praised Trump’s controversial statements made after white supremacists had a violent rally in Charlottesville and also said he agreed with Trump that professional football players should stand during the national anthem. Neither issue has anything to do with the Treasury Department.
Former treasury secretary Larry Summers wrote in a Twitter post that “Mnuchin may be the greatest sycophant in Cabinet history.”
Especially in the early days of his presidency, aides delivered the president daily packages of news stories filled with positive coverage and Trump began meetings by boasting about his performance, either as president or in winning the White House, according to one person who attended several Oval Office gatherings with him.
