Fire and Fury: Inside the Trump White House by Michael Wolff:
Many candidates for president have made a virtue of being Washington outsiders; in practice, this strategy merely favors governors over senators. Every serious candidate, no matter how much he or she disses Washington, relies on Beltway insiders for counsel and support. But with Trump, hardly a person in his innermost circle had ever worked in politics at the national level—his closest advisers had not worked in politics at all. Throughout his life, Trump had few close friends of any kind, but when he began his campaign for president he had almost no friends in politics. The only two actual politicians with whom Trump was close were Rudy Giuliani and Chris Christie, and both men were in their own way peculiar and isolated. And to say that he knew nothing—nothing at all—about the basic intellectual foundations of the job was a comic understatement. Early in the campaign, in a Producers-worthy scene, Sam Nunberg was sent to explain the Constitution to the candidate: “I got as far as the Fourth Amendment before his finger is pulling down on his lip and his eyes are rolling back in his head.”
Almost everybody on the Trump team came with the kind of messy conflicts bound to bite a president or his staff. Mike Flynn, Trump’s future national security advisor, who became Trump’s opening act at campaign rallies and whom Trump loved to hear complain about the CIA and the haplessness of American spies, had been told by his friends that it had not been a good idea to take $45,000 from the Russians for a speech. “Well, it would only be a problem if we won,” he assured them, knowing that it would therefore not be a problem.
