Pelosi was joined on the visit by other US officials.

It's not clear how long the congressional representatives will be in Ukraine.

A representative for Pelosi's office said that Barbara Lee and Bill Keating did not enter the country. They will travel with the delegation to Poland and Warsaw.

In a press release posted early Sunday morning, Speaker Pelosi said: "Our delegation traveled to Kyiv to send an unmistakable and resounding message to the entire world: America stands firmly with Ukraine." President Zelenskyy thanked the United States for the assistance that they have provided.

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.

Our delegation appreciated the leadership of President Zelenskyy and the courage of the Ukrainian people in the fight against Russia.
