UChicago Law professor Claudia Flores has spent a career advocating for human rights of vulnerable populations around the world, from East Timor to Mexico.

But her latest work revealed the hidden abuse of migrant children detained at the U.S. border and separated from their parents in a report titled, “I’m going to take you back to the river so you can die.”

Flores discusses her report produced in partnership with the ACLU, the history and future of immigration policy in the U.S., and her career as a human rights advocate.
