Sharply at odds with liberal justices, the Supreme Court’s conservative majority seemed ready Tuesday to allow the Trump administration to abolish protections that permit 660,000 immigrants to work in the U.S., free from the threat of deportation.

That outcome would “destroy lives,” declared Justice Sonia Sotomayor, one the court’s liberals who repeatedly suggested the administration has not adequately justified its decision to end the seven-year-old Deferred Action for Childhood Arrivals program. Nor has it taken sufficient account of the personal, economic and social disruption that might result, they said.

But there did not appear to be any support among the five conservatives for blocking the administration. The nine-member court’s decision is expected by June, at the height of the 2020 presidential campaign.

President Donald Trump said on Twitter that DACA recipients shouldn’t despair if the justices side with him, pledging that “a deal will be made with the Dems for them to stay!” But Trump’s past promises to work with Democrats on a legislative solution for these immigrants have led nowhere.

The president also said in his tweet that many program participants, brought to the U.S. as children and now here illegally, are “far from ‘angels,’” and he claimed that “some are very tough, hardened criminals.” The program bars anyone with a felony conviction from participating, and serious misdemeanors may also bar eligibility.
