Giuliani tweeted. "Jerry’s diarrhea of the mouth produced a year of statements showing pre-judgement."

Nadler has maintained since Mueller concluded his investigation that "there was in plain sight open collusion with the Russians," even if it was not criminal.

"His lack of judiciousness was evident when he was overheard on Amtrak prematurely planning impeachment," Giuliani added, referring to Nadler's phone conversations on an Amtrak train that were overheard and reported last year by The Federalist.

In the phone conversations, Nadler reportedly was heard discussing plans for the Judiciary Committee to hold Trump "accountable" for any possible violations of the law as well as plans to pursue a possible investigation into Supreme Court Justice Brett Kavanaugh Brett Michael KavanaughOvernight Health Care: US coronavirus deaths hit 200,000 | Ginsburg's death puts future of ObamaCare at risk | Federal panel delays vote on initial COVID-19 vaccine distribution Senate GOP sees early Supreme Court vote as political booster shot Trump says he'll make Supreme Court pick on Saturday MORE to determine whether Kavanaugh had committed perjury during his Senate confirmation hearing last year.

Kavanaugh's impeachment, Nadler said at the time, was a possibility.

"The worst-case scenario — or best case depending on your point of view — you prove he committed perjury, about a terrible subject and the Judicial Conference recommends you impeach him. So the president appoints someone just as bad," Nadler reportedly said at the time, referring to Kavanaugh.
