Two days before FBI director James Comey rocked the world last week, Rudy Giuliani was on Fox, where he volunteered, un-prodded by any question: “I think he’s [Donald Trump] got a surprise or two that you’re going to hear about in the next few days. I mean, I’m talking about some pretty big surprises.”

Pressed for specifics, he said: “We’ve got a couple of things up our sleeve that should turn this thing around.”

The man who now leads “lock-her-up” chants at Trump rallies spent decades of his life as a federal prosecutor and then mayor working closely with the FBI, and especially its New York office. One of Giuliani’s security firms employed a former head of the New York FBI office, and other alumni of it. It was agents of that office, probing Anthony Weiner’s alleged sexting of a minor, who pressed Comey to authorize the review of possible Hillary Clinton-related emails on a Weiner device that led to the explosive letter the director wrote Congress.
