The SBU notified Zelensky's former press secretary, Yulia Mendel, in absentia, of suspicion of treason. The Security Service of Ukraine and the Prosecutor General's Office reported in absentia that the former press secretary of the President of Ukraine, Volodymyr Zelensky, Yulia Mandel, is suspected of treason and justifying Russian aggression. She is accused of "treason under military law" (Part 2 of Article 111 of the Criminal Code of Ukraine), as well as "justification, recognition as legitimate and denial of Russian armed aggression against Ukraine and glorification of its participants" (Parts 2 and 3 of Article 436-2). According to the researchers, in public speeches and postings on social networks, Mendel discredited Ukraine in the international arena and justified the Russian authorities and the total war they started. The SBU stated that the conclusions of the investigation were confirmed by the results of the tests. "Since the suspect is outside of Ukraine, comprehensive steps are being taken to bring her to justice," the SBU said in a statement. Yulia Mendel was Vladimir Zelensky's press secretary from June 2019 to July 2021. Before being appointed to this position, she worked as a journalist, collaborating with Ukrainian and foreign media, including The New York Times and Politico. In May 2026, she gave an interview to conservative American journalist Tucker Carlson, in which she criticized Vladimir Zelensky.
