As more details from the documents dumped on Congress by President Trump’s personal attorney, Rudolf Giuliani, are released, it continues to spell big trouble for Joe Biden and his son, Hunter.

A batch of newly released documents, including court filings as well as notes from interviews conducted by Rudy Giuliani, have put the spotlight back on the Biden family’s dealings in Ukraine—even as the House Democrats’ impeachment probe zeroes in on President Trump’s push to convince Kiev to investigate them.

The “Giuliani Files” have raised more questions about how much money Joe Biden’s son Hunter made while serving on the board of a Ukrainian natural gas firm at the center of the controversy, with one estimate putting the figure in the “millions.”

Among the documents, obtained by Fox News, are notes from an interview Giuliani conducted with fired Ukrainian prosecutor Viktor Shokin earlier this year, in which he claimed he was told by former U.S. Ambassador to Ukraine Geoffrey R. Pyatt, to back off an investigation involving that firm, Burisma Holdings, and its founder. According to interview notes, Shokin claimed Pyatt – who is currently the ambassador to Greece — told him to handle that investigation “with white gloves.”

Giuliani’s notes also claim that in that interview, Shokin claimed that former Ukrainian President Petro Poroshenko told him he should not investigate Burisma, “as it was not in the interest of Joe and/or Hunter Biden.” Shokin claimed Poroshenko told him that due to his investigation, Joe Biden held “up to one billion dollars in U.S. aid to Ukraine.” Poroshenko eventually removed Shokin.

Dems Rally Around Former Veep

Biden’s supporters have maintained that his intervention prompting the firing of Shokin had nothing to do with his son, but rather was tied to the corruption concerns. The Biden campaign has also slammed Giuliani and blasted media outlets for giving him air time. The campaign wrote to NBC News, CBS News, Fox News, and CNN to voice “grave concern that you continue to book Rudy Giuliani on your air to spread false, debunked conspiracy theories on behalf of Donald Trump.”

“The substance of President Trump and Rudy Giuliani’s claims have been roundly discredited,” Biden Deputy Campaign Manager Kate Bedingfield said last week. “This is not a claim from the campaign or Joe Biden. This is an irrefutable fact.”

However, the notes of the interview found within the “Giuliani Files,” seem to dispute this account. At the time, according to the interview, Shokin was investigating Mykola Zlochevsky, the former minister of ecology and natural resources of Ukraine. Zlochevsky also happens to be the founder of Burisma.

Hunter Biden was appointed to the board of the firm, which Shokin claimed was an appointment made by Zlochevsky “in order to protect himself.”
