Oil for terrorists, treason, in absentia arrest, and wife with Russian passport
On February 2, 2021 — the first case in Ukraine's history of personal sanctions by the National Security and Defense Council against a sitting MP: for selling petroleum products to the terrorist organizations "LPR" and "DPR." On May 20, 2021, the Security Service of Ukraine obtained a court permit for detention; on April 7, 2022, Kozak was arrested in absentia without the right to bail. He is internationally wanted — likely in Belarus or Russia. His common-law wife, Natalia Lavrenyuk, is a Russian citizen; after sanctions, she changed her name to "Svitlana Zhuchkova." Most of Kozak's business and property have been transferred to her. In 2022, the United States imposed separate sanctions for "assisting Kremlin political objectives." OCCRP established that Kozak earned millions from the sale of an oil field in the Russian Federation. Bellingcat named him a Russian agent.
