On September 29, Rudy Giuliani appeared on ABC News, waving a fistful of papers. The document in his hand was an affidavit from Viktor Shokin, a former top Ukrainian prosecutor who was fired in 2016 under international pressure due to his failure to combat corruption. Giuliani asserted that the affidavit supported his debunked claim that former Vice President Joe Biden had forced Shokin’s ouster to prevent Shokin from investigating a company tied to Biden’s son.
