From a story on politico.com by Gabriel Gavin headlined “Zelenskyy’s battle to win over Washington”:

The last time Volodymyr Zelenskyy visited Washington, he received a hero’s welcome. Speaking at a December joint session of Congress, the Ukrainian president, wearing his trademark green army sweater, was forced to pause his speech as senators and representatives, Democrats and Republicans, gave him a standing ovation.

“Your support is crucial to get to the turning point to win on the battlefield,” he told U.S. politicians at the time.
