Today, President Joe Biden is in Poland. He visited US troops there who are defending NATO’s eastern flank, and he met with Ukrainians who have recently been evacuated to Poland, fleeing Russian attacks. The US continues to support Ukraine’s effort to defend itself in the face of Russian aggression while also seeking a way to deescalate the conflict through diplomacy. Deputy Secretary of State Wendy Sherman is the nation’s second-ranking diplomat and spoke to The World from Washington.
