Two years ago, the Trump administration decided to end Deferred Action for Childhood Arrivals (DACA) — a policy enacted under President Obama that deferred the deportation of undocumented people brought to the United States as children. Earlier this week, the Supreme Court heard challenges to that decision and was faced with the questions: can the Court even review the decision to end DACA, since it was an action taken by the Department of Homeland Security, an executive branch agency? If it can, was the decision to rescind DACA legal? And is DACA itself legal and constitutional? Brianne Gorod of the Constitutional Accountability Center and Josh Blackman of the South Texas College of Law Houston join host Jeffrey Rosen to dive into the questions.
