This week, as a federal judge ordered the Trump administration to reunite thousands of migrant children separated from their parents by the Department of Homeland Security, protests have erupted around the country. Joy Reid and her panel discuss the moments leading up to Saturday’s ‘Families Belong Together’ events. Then: It is still unclear how the government will comply with a federal judge’s order to reunite migrant children already separated from their parents. Laura Peña, former ICE assistant chief counsel, and Rep. Pramila Jayapal, join Joy Reid to discuss. Plus: Donald Trump’s supporters have vilified Supreme Court Justice Anthony Kennedy, but his retirement grants the Trump base the biggest gift of all—allowing the president to fill a second Supreme Court vacancy as the future of Roe v. Wade hangs in the balance. And: Thousands of protesters participating in Saturday’s ‘Families Belong Together’ rallies in over 770 cities across America are demanding positive outcomes for the over 2,000 children still in government custody. Joy Reid and her panel discuss the impact of this issue on the 2018 midterm elections. Next: Rep. John Lewis spoke at Atlanta’s ‘Families Belong Together’ march telling participants, ‘As a nation and as a people we can do much better,’ than separating migrant children from their mothers. Finally: With ‘Families Belong Together’ marches underway nationwide, Joy Reid speaks to MSNBC reporters in the field on the thousands gathering to support migrant children separated from their parents, and the reunification of immigrant families.
