Ukrainian President Volodymyr Zelensky presented Congress with a flag signed by Ukrainian soldiers as a gift to say thank you for the weapons that had been sent.
The flag was given to Zelensky on Tuesday in the frontline city of Bakhmut in eastern Ukraine.
"This flag is a symbol of our victory in this war. We stand, we fight, and we will win because we are united. Ukraine, America, and the entire free world," Zelensky said.
In return, House Speaker Nancy Pelosi gave Zelensky a folded US flag that had flown over the Capitol building on Wednesday.
Members of Congress gave Zelensky a standing ovation and applauded the exchange.
