MSNBC’s Chief Legal Correspondent Ari Melber reports on The Flores Agreement, a decades-old court settlement that is now more important than ever. The case controls how immigrant minors are treated in detention -- and is central to Trump’s family separation crisis. In this special report, Melber examines how Trump's immigration agenda is thwarted by this Clinton-era case, how Trump actually echoes Obama on the immigration ruling but differs on protecting human rights, and what Congress can do to reform the entire system.
