Three years into the war with Russia, President Zelensky appears to have become embroiled in a personal feud with the leader of Ukraine’s most powerful ally.

Volodymyr Oleksandrovych Zelensky was a comedian with no political experience when he announced that he would be running in Ukraine's 2019 presidential election. Six years later, and he is now an embattled wartime leader and a symbol of Ukrainian defiance of Russian aggression.

Keith Kellogg and President Volodymyr Zelensky were expected to discuss possible paths to ending the war and ways to defuse tensions between Washington and Kyiv.
