Volodymyr Zelenskyy has a problem: Nobody wants the hardest job in Washington.

The Ukrainian president is struggling to find someone of sufficient influence to represent Kyiv to the Trump administration, with prospective candidates proving reluctant to take on the grueling assignment at a critical moment in the war, according to two former senior Ukrainian officials and four lawmakers.

The need to replace the previous envoy, Olga Stefanishyna, helped trigger Zelenskyy’s still-incomplete government reshuffle. Stefanishyna was formally dismissed on Aug. 3 over impending embezzlement charges.
