The Supreme Court’s conservative majority seems prepared to allow the Trump administration to end a program that allows some immigrants to work legally in the United States and protects them from deportation.

There did not appear to be any support among the five conservatives in extended arguments for blocking the administration’s decision to wind down the Deferred Action for Childhood Arrivals program. It currently protects 660,000 immigrants who came to the United States as children and are here illegally.

Chief Justice John Roberts and Justice Brett Kavanaugh were among the justices who indicated that the administration has provided sufficient reason for wanting to do away with the program. Justices Neil Gorsuch and Samuel Alito raised questions about whether courts should even be reviewing the executive branch’s discretionary decisions.

The high court’s decision is expected by June, at the height of the 2020 presidential campaign.

The program was begun under President Barack Obama. The Trump administration announced in September 2017 that it would end DACA protections, but lower federal courts have stepped in to keep the program alive.
