Serhiy Leshchenko, a member of the Ukrainian Parliament, was a common thread involved in Democratic opposition research efforts into former Trump campaign Chairman Paul Manafort. Leshchenko, along with Artem Sytnyk, the director of Ukraine’s National Anti-Corruption Bureau, was responsible for publicly disclosing the contents of the Ukrainian “black ledger,” which implicated Manafort, to the media.

Leshchenko also served as a source for various individuals, including journalist Michael Isikoff and DNC operative Alexandra Chalupa. In addition, Leshchenko served as a direct source of information for Fusion GPS—and their hired researcher—former CIA contractor Nellie Ohr.

When pressed, Nellie said she recalled them “mentioning someone named Serhiy Leshchenko, a Ukrainian.” She later admitted she knew of Leshchenko prior to her time at Fusion as he was a “very well-known, Ukrainian, anti-corruption activist” and said she had followed him in the press.

Leshchenko revealed the existence in 2016 of the so-called Ukrainian “black ledger,” which allegedly contained a list of secret payments made by Ukraine’s pro-Russian Party of Regions to Manafort among many others.

Leshchenko had adopted a strong anti-Trump stance, telling the Financial Times in August 2016 that “a Trump presidency would change the pro-Ukrainian agenda in American foreign policy” and that it was “important to show not only the corruption aspect, but that he is [a] pro-Russian candidate who can break the geopolitical balance in the world.” Leschenko noted that the majority of Ukrainian politicians were “on Hillary Clinton’s side.”
