President Trump is weighing whether to terminate an Obama-era directive that grants a reprieve to thousands of young illegal immigrants each year, ahead of a deadline set by a 10-state coalition that plans to sue the administration if the program remains in place.

The Deferred Action for Childhood Arrivals program, which currently protects nearly 800,000 unauthorized immigrants from deportation, has been a headache for Trump since the beginning of his presidency. The president has spent months vacillating between his unforgiving stance on illegal immigration and a compassionate approach toward so-called Dreamers, despite promising to undo all of Barack Obama’s immigration-related executive actions during the 2016 campaign.
