Shortly before the election, Giuliani claimed that he heard about big problems coming soon for Democratic nominee Hillary Clinton. That was shortly before then-FBI Director James Comey announced he was reopening the criminal probe into Clinton’s email server, which didn’t lead to any criminal charges. The polls shifted after Comey’s comments, and Clinton has said it was a main reason for her defeat.
…Democrats accused Giuliani, who was previously the US attorney in Manhattan, of tapping his network of friends and contacts in law enforcement to get tips about Clinton, which he used to attack her in the press. Comey also raised this possibility in a closed-door deposition with House lawmakers last year, and confirmed that he launched the leak investigation before he was fired in May 2017.
