Secretary of Labor Tom Perez discusses the stagnation in Congress over comprehensive immigration reform and defends the legality of President Obama's immigration executive actions, which will be argued before the Supreme Court on Monday as the Justices examine DACA (Deferred Action for Childhood Arrivals) and DAPA (Deferred Action for Parental Accountability).
