Joy Reid leads this episode of The ReidOut with Bill Barr saying in a stunning interview that Donald Trump probably committed a serious crime. Joy and her panel discuss how today we learned much more about the many classified documents Trump stole and stashed at Mar-a-Lago. Plus, we revisit President Biden's searing and completely accurate warning about the threat posed by Trump and his violent, election-denying followers in the president's prime time Thursday speech. Next, the mayor of Jackson, Mississippi, Chokwe Antar Lumumba, joins us on day five of a national disgrace--the state capital where the water is not safe to drink, and citizens are being advised to keep their mouths closed when taking a shower. Finally, Joy and her guests agree: Serena Williams won the week! All this and more in this edition of The ReidOut on MSNBC.
