Saturday on PBS NewsHour Weekend, Russians continue their attack on Ukraine, focusing in on Mariupol. Ukrainian President Volodymyr Zelenskyy announced that Secretary of State Blinken and Defense Secretary Lloyd Austin would meet with him Sunday in Kyiv. Then, we take a look at how very few mask mandates remain in the U.S. as COVID vaccines are still unavailable for the youngest children. Also, we take a look back at how musical mashups began and how they are becoming more accessible.
