Democrats have begun talking about the importance of a Ukrainian victory over Russia amid questions about President Joe Biden’s leadership of the Western response to the Kremlin’s invasion.

House Speaker Nancy Pelosi (D-CA) led a group of Democratic lawmakers on a surprise visit to Ukrainian President Volodymyr Zelensky over the weekend. “Our delegation traveled to Kyiv to send an unmistakable and resounding message to the entire world: America stands firmly with Ukraine,” she said in a statement afterward.
