WASHINGTON (AP) — Adding a high-stakes immigration case to its election-year agenda, the Supreme Court said Friday it will decide whether President Donald Trump can terminate an Obama-era program shielding young migrants from deportation.

The justices’ order sets up legal arguments for late fall or early winter, with a decision likely by June 2020 as Trump campaigns for re-election. The president ordered an end to the program known as DACA in 2017, sparking protests and a congressional effort to salvage it.

That effort failed, but federal courts in California, New York, Virginia and Washington, D.C., have blocked him from ending it immediately. A federal judge in Texas has declared the program is illegal, but refused to order it halted .

The program — Deferred Action for Childhood Arrivals — protects about 700,000 people, known as dreamers, who were brought to the U.S. illegally as children or came with families that overstayed visas.

The DACA protections seem certain to remain in effect at least until the high court issues its decision.
