“In recent weeks, FBI agents in New York contacted witnesses and asked new questions about Giuliani’s efforts in Ukraine and possible connections to Russian intelligence, according to a person briefed on the matter. The FBI investigators, who have spoken to at least one witness previously months ago, came back to ask new questions recently about possible origins of emails and documents related to Hunter Biden that appear similar to those that the New York Post reported that Giuliani and others helped provide. CNN has previously reported that the ongoing probe is examining whether Giuliani is wittingly or unwittingly part of a Russian influence operation, according to people briefed on the matter. But questions about that probe have been out of the spotlight as Giuliani stepped into focus as the campaign’s chief post-election lawyer. One source close to Trump countered that Giuliani is an overzealous defender of the president” – CNN.
