Inside the Pentagon, early fears Trump will micromanage the generals more than Obama did: Trump has signaled some intent to second-guess military leadership. Last year, for instance, he said of the Islamic State group “I know more about ISIS than the generals do, believe me.” And some experts say that, during the campaign to be president, the business mogul revealed important insights about his management style. Turnover among his top advisers was common, and Trump often ignored recommendations from those closest to him.
“He’s micromanaged everything. He disregards the advice of the people working for him, and he makes the final decision himself. So it's hard to think that he would change that style,” said Larry Korb, a defense expert with the Center for American Progress, a think tank in Washington.
As an executive, Trump was often eager to stay involved in the day-to-day operations of his businesses, according to a biographer. He "didn’t surrender any actual power. He signed checks, read documents, interrogated everyone about assignments and did not hesitate to call the people they were calling,” wrote Gwenda Blair, author of “The Trumps,” a book about his family published in 2000.
