Donald Trump was seen by many as pandering to Russian President Vladimir Putin at the G20 summit in Osaka, Japan, including asking Putin not to meddle in U.S. elections in an apparently joking manner. Joy Reid and her panel discuss the U.S. president’s reported friendliness with dictators at the summit. Plus: Sen. Kamala Harris powerfully criticized former Vice President Joe Biden’s past record of ‘reaching across the aisle’ to segregationists, and working against school busing programs, during the first Democratic debate. Joy and guests discuss how both Harris and Biden are working to secure the black vote. Then: This has been a critical week on the issue of immigration, as the Supreme Court readies to take up a case that could impact the future of DACA. Finally: Rob Reiner, director, actor and activist, is back with part three of his NowThis series explaining the key findings of the Mueller report.  All this and more in this Saturday edition of AM JOY on MSNBC.Learn more about your ad choices.
