The government shutdown sparked by Donald Trump clashing with congressional leaders over his border wall has entered it's third week, impacting the salaries of hundreds of thousands of federal workers. Joy Reid and her panel discuss the harm to national parks, cut-backs in important services, and other ramifications, plus the fact that experts say a wall is not an effective means of implementing border security. Plus: Donald Trump has been sharing what many see as talking points based on Russia's narrative of events concerning that nation's invasion of Afghanistan. Will Robert Mueller consider this development as part of his ongoing investigation? And: Rep. Pramila Jayapal joins Joy on why she believes Medicare for All is the best complement to Obamacare Americans need now to provide comprehensive health insurance to as many people as possible. All this and more in this Sunday edition of AM JOY on MSNBC.
