Joy Reid leads this edition of The ReidOut with the civilian tragedy that continues to unfold as Vladimir Putin's war in Ukraine enters its third week on Thursday. Maksym Borodin, a city council member in Mariupol, Ukraine, joins Joy to discuss. Plus, it is not just Ukrainians fleeing. We also analyze how Russians are leaving their own homeland before the new Iron Curtain fully descends on Russia due to Putin's war. We next turn to Western nations warning that Putin appears ready to commit new and even more horrific atrocities in Ukraine. Yesterday, the White House raised the possibility that Russia could soon use chemical or biological weapons in violation of international law. Finally, we report on the effort to house the millions of Ukrainians who have become refugees, with over 1.4 million having crossed into Poland alone. All this and more in this edition of The ReidOut on MSNBC.
