President Joe Biden embarks on an emergency mission to Europe

Joy Reid leads this episode of The ReidOut with one of the most high-stakes presidential trips in recent memory. President Joe Biden is embarking on an emergency mission to Europe, meeting with NATO leaders in Brussels, and then heading to Poland--a country on the front lines of the humanitarian and military crisis in Ukraine. It is perhaps the most important moment in Biden's presidency so far, a moment that will punctuate world history for decades to come. Marie Yovanovitch, former U.S. Ambassador to Ukraine, joins The ReidOut to discuss. Next we turn to Ginni Thomas, who has been a steadfast advocate and defender of her husband, Supreme Court Justice Clarence Thomas, since his contentious confirmation hearing in 1991, when he faced credible allegations of sexual harassment of Anita Hill and other women. The bombshell revelation from The Washington Post and CBS that she sent 29 text messages to Donald Trump's chief-of-staff Mark Meadows promoting QAnon conspiracy theories to justify overturning the 2020 election, has now cast yet another shadow over Thomas and the supposed "impartiality" he claims to espouse on the bench. Joy Reid and our legal experts analyze these developments. Joy also critiques U.S. Senator Josh Hawley. All this and more in this edition of The ReidOut on MSNBC.
