President Volodymyr Zelensky rallied Congress to Ukraine’s cause Wednesday.

In a pointed message to President Joe Biden, Zelensky suggested that “today, it is not enough to be the leader of the nation. Today, it takes to be the leader of the world. Being the leader of the world means to be the leader of peace.” The Ukrainian president then addressed Biden directly: “You are the leader of the nation, of your great nation. I wish you to be the leader of the world.”
