Following the visit, Pelosi and the delegation said in a statement: "Our Congressional Delegation had the solemn opportunity and extraordinary honor of meeting with Ukrainian President Volodymyr Zelenskyy and other top Ukrainian officials in Kyiv."

"Our delegation traveled to Kyiv to send an unmistakable and resounding message to the entire world: America stands firmly with Ukraine.  Our meeting with President Zelenskyy began with him thanking the United States for the substantial assistance that we have provided," the statement said.

"He conveyed the clear need for continued security, economic and humanitarian assistance from the United States to address the devastating human toll taken on the Ukrainian people by Putin's diabolic invasion – and our delegation proudly delivered the message that additional American support is on the way, as we work to transform President Biden’s strong funding request into a legislative package," the statement said. 

The statement further said: "Our delegation conveyed our respect and gratitude to President Zelenskyy for his leadership and our admiration of the Ukrainian people for their courage in the fight against Russia’s oppression."
