Undocumented immigrants who were brought to the United States as children have reason to be disappointed by the Supreme Court’s announcement on Friday that it will consider how President Trump went about ending the popular Deferred Action for Childhood Arrivals program, known as DACA.

The court could have declined to review challenges to the initiative, which remains available to about 800,000 so-called Dreamers who have waited years for a permanent solution from Congress.

The public largely supports DACA and its beneficiaries, and lawmakers are working to expand its protections through a path to citizenship.

The justices have remained silent on pending appeals challenging the program for many months — and have even rebuffed an earlier attempt to fast-track a case urging them to declare that shutting down DACA’s would be lawful. Why the sudden urgency to step in now?
