Joy Reid leads this episode of The ReidOut with the unified display of solidarity in Brussels, where Western leaders stood shoulder to shoulder in an extraordinary series of summits hosted by NATO, the Group of Seven industrialized nations, and the European Union. Western leaders continue to roll out a series of measures to increase the pressure on Russian President Vladimir Putin, while avoiding steps that could lead to a wider war on the continent. Joy Reid and her panel discuss what could happen if Putin escalates his war against Ukraine with chemical weapons. Next we turn to the Supreme Court confirmation hearings for Judge Ketanji Brown Jackson, which have concluded. Through it all, Judge Jackson remained poised with a graceful temperament. U.S. Sen. Mazie Hirono joins us with her commentary on her own questions for Judge Jackson, and more. Plus, we end with a Moment of Joy, featuring a seven-year-old Ukrainian girl who has inspired a multitude with her voice, even as a refugee. All this and more in this edition of The ReidOut on MSNBC.
