Flipping A District in Calif; Sonia Nazario on Migrant Children; Harold Meyerson on SCOTUS

The only Republican in the House from LA County, Steve Knight, is facing a strong challenge from first-time Democrat Katie Hill. He's against Obamacare; she's for Medicare for All -- and her chances look good. Dana Goodyear of the New Yorker reports. Plus: Despite Trump's reversal on family separation at the border, the crisis continues. Sonia Nazario, Pulitzer Prize winning journalist and author of "Enrique's Journey," a book that detailed experiences of Latin American children immigrating to the US, joins us today to talk about Trump's fake news, the experiences of migrants, and how we might improve family detention while people are waiting for their asylum hearings. Also: a really bad week at the Supreme Court Unions: for unions, for stopping gerrymandering, and for replacing Justice Anthony Kennedy: Harold Meyerson of the American Prospect reports on what we should do now.
