President Joe Biden is hosting Ukrainian President Volodymyr Zelensky in Washington, D.C., at the White House. It’s the Ukrainian president’s second visit since Russia’s invasion last year.

Zelensky first made a surprise visit to the United States in December during the battle of Bakhmut, which ultimately ended in a Ukrainian defeat. After meeting with Biden personally, he also spoke to Congress, presenting it with a Ukrainian flag signed by defenders of the city.
