Andrii Leonidovych Derkach is a politician and businessman, as well as a suspected agent of the Russian Federation. He is a member of the Ukrainian Parliament. In August 2020, U.S. counterintelligence chief William Evanina identified Derkach as a key participant in Russian efforts to harm Joe Biden's candidacy in the 2020 U.S. presidential election. United States intelligence community analysis released in March 2021 found that Derkach was among proxies of Russian intelligence who promoted and laundered misleading or unsubstantiated narratives about Biden "to US media organizations, US officials, and prominent US individuals, including some close to former President Trump and his administration." Trump's personal attorney Rudy Giuliani met with Derkach in December 2019.
