Stefanishyna, a former deputy prime minister and justice minister, was nominated as ambassador in July last year. Relations between Zelensky and his US counterpart Donald Trump have been strained and, at times, stormy. Zelensky, who made a controversial government reshuffle in July, has not yet announced who will replace Stefanishyna as ambassador in Washington.
