Ukrainian President Zelenskyy met with U.S. envoy Steve Witkoff and European officials in Norway in a bid to avoid a further diplomatic rupture with President Trump. Over the past week, Trump has criticized Zelenskyy over Ukraine's efforts to inflict heavy losses on Russia. The meeting was aimed at easing tensions ahead of Witkoff's meeting with Vladimir Putin in Russia. Nick Schifrin reports.

The war of words between President Trump and Ukraine's Volodymyr Zelenskyy reached another fever pitch on Monday. Trump again excoriated the embattled Ukrainian leader, putting more pressure on Zelenskyy than on the man in Moscow who started this war, Vladimir Putin. The president's comments come after the U.S. has limited a key technology that Ukraine relies on. Nick Schifrin reports.
