Ukraine’s President Volodymyr Zelenskyy said Wednesday (August 27, 2025) he had appointed a former Deputy Prime Minister, Olga Stefanishyna, as Kyiv’s new ambassador to the United States, as Washington-backed efforts to halt the war with Russia intensify.

Zelenskyy signed a decree unexpectedly naming Ms. Stefanishyna, who is also a former Justice Minister, to the key post, he said in his evening address posted on social media.
