ZAPORIZHZHIA, Ukraine — U.S. Speaker of the House of Representatives Nancy Pelosi has met with Ukraine’s president during a visit to the country’s embattled capital, Kyiv.

Pelosi, second in line to the presidency after the vice president, is the highest-ranking American leader to visit Ukraine since the start of the war, and her visit marks a major show of continuing support for the country’s struggle against Russia.

Footage released early Sunday by President Volodymyr Zelenskyy’s office showed Pelosi in Kyiv with a Congressional delegation including Jason Crow, Jim McGovern and Adam Schiff.

Zelenskyy greeted the delegation outdoors before they adjourned to a meeting room where he said, “I am grateful to you for this signal of strong support from the United States, the people, and Congress — bicameral and bipartisan support.”

“This shows that the United States today is a leader in strong support for Ukraine during the war against the aggression of the Russian Federation,” Zelenskyy said.

Pelosi told Zelenskyy: “We believe that we are visiting you to say thank you for your fight for freedom.”

“We are on a frontier of freedom and your fight is a fight for everyone. Our commitment is to be there for you until the fight is done,” Pelosi added.

The visit was not previously announced.
