U.S. House of Representatives Speaker Nancy Pelosi has led a congressional delegation to Kyiv to meet with Ukraine’s president before heading to Poland for talks with officials there on Sunday, AP reported.

Her visit to Kyiv marks a major show of continuing support for Ukraine’s struggle against Russia.

“Our delegation traveled to Kyiv to send an unmistakable and resounding message to the entire world: America stands firmly with Ukraine,” Pelosi said in a statement released Sunday.

Footage released by Ukrainian President Volodymyr Zelenskyy’s office showed Pelosi and other U.S. legislators in Kyiv. In video later released by Pelosi’s office, the speaker and Zelenskyy both thanked each other for their support in the war.

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 aforesaid congressional delegation included Democratic Reps. Gregory Meeks of New York who chairs the House Foreign Affairs Committee; Adam Schiff, of California who chairs the House Intelligence Committee; Jim McGovern of Massachusetts who chairs the House Rules Committee; Jason Crow of Colorado; Barbara Lee of California; and Bill Keating of Massachusetts.
