“I cannot overstate how devastating this is,” said Karen Tumlin, founder and director of Justice Action Center, which was part of the legal team representing the migrants.

The Supreme Court on Friday stayed a lower court order that blocked the Trump administration from deporting roughly 500,000 migrants from Cuba, Nicaragua, and Venezuela.

Justice Jackson wrote that the court's order would "have the lives of half a million migrants unravel all around us before the courts decide their legal claims".
