'I thought this must be a scam or a shake-down, so I reported it to the police,' Giuliani, 76, said in an interview after being pranked by the bikini-clad comedian.

U.S. attorney Geoffrey S. Berman said he was refusing to leave his post and his ongoing investigations would continue.

The recording contradicts the president's statements that he did not know the Giuliani associates Lev Parnas or Igor Fruman, key figures in the Ukraine investigation who were indicted last year on campaign finance charges.

Lev Parnas, an associate of Rudy Giuliani, made several potentially explosive claims in a televised interview Wednesday night with MSNBC's Rachel Maddow.

Among the documents, obtained from Rudy Giuliani associate Lev Parnas, is a screenshot of a previously undisclosed letter from Giuliani to Ukrainian President Volodymir Zelenskiy before he took office.

Lev Parnas wants to turn over to the House intelligence committee documents and data that were seized by the government when he was arrested in October, his attorney, Joseph Bondy, said in a letter to U.S. District Court Judge Paul Oetken on Monday.

On Wednesday, December 18, 2019, Trump was impeached for what Democrats considered “high crimes and misdemeanors” as laid out in the Constitution. The House voted 230-197 on the first charge, 229-198 on the second, with one Democrat voting “present″ each time.

Giuliani's interview comes as Trump is facing near-certain impeachment Wednesday by the House.

Trump said Giuliani had not yet told him what information he has gathered, though the president said he’s heard it was plentiful.

An independent Ukrainian lawmaker said on Thursday he had met U.S. President Donald Trump's personal lawyer in Kyiv to discuss the alleged misuse of U.S. taxpayer money by Ukrainian state bodies.
