RIGHT TO DISTRUST NYC; WRONG TO ANNOUNCE:

Late that [Octyober], Giuliani told Fox News that the trailing Republican nominee had "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."

Just two days later, then-FBI director James Comey revealed the bureau had reopened its probe into Clinton's emails, based on the possible discovery of new communications on a laptop belonging to disgraced New York politico Anthony Weiner. The news jolted the campaign with a particularly strong boost from the New York Times, which devoted two-thirds of its front page to the story -- and the notion it was a major blow to Clinton's prospects.

It was later reported that Comey was motivated to make the unusual announcement about the laptop because he feared leaks from the FBI's New York field office, which, according to Reuters, had "a faction of investigators based in the office known to be hostile to Hillary Clinton." Indeed, Giuliani bragged immediately after that he had sources in the FBI, including current agents. [...]

There are many reasons for Trump's victory, but experts have argued the FBI disclosures were decisive. In 2017, polling guru Nate Silver argued that the Comey probe disclosure cost Clinton as many as 3-4 percentage points and at least one percentage point, which would have flipped Pennsylvania, Michigan and Wisconsin and handed her the Electoral College.
