President Biden is in Warsaw, Poland, today, where he’s giving a major address on U.S. support for Ukraine ahead of the first anniversary of Russia’s invasion. Biden is also meeting with leaders of the nine countries on NATO’s eastern flank, including Polish President Andrzej Duda. Biden’s trip to Poland comes one day after he announced a half-billion dollars’ worth of additional U.S. weaponry for Ukraine during a surprise visit to Kyiv.
