When we look back on the Age of Trump, we'll remember a vivid chapter from James Comey's new book. The FBI director is seized by "the strangest feeling" upon meeting the president-elect in the gilded palace he called home. He looks at the Donald and he sees a Mafia don.

Then the newly inaugurated president invites Comey to dine alone with him at the White House, and the initiation ceremony starts. We know what's coming.

In the opening pages of "A Higher Loyalty," the young Comey, a federal prosecutor in New York, not yet 30 years old, is being schooled in the traditions of mob rules by Salvatore "Sammy the Bull" Gravano, the highest-ranking American mobster to turn government witness. Comey sums them up: "The silent circle of assent. The boss in complete control. Loyalty oaths."
