A federal judge has temporarily restricted the Trump administration's ability to quickly deport migrants who have legally entered the U.S. through humanitarian programs.

A federal judge on Friday paused the Trump administration’s efforts to fast-track the deportation of migrants who legally entered the United States through humanitarian parole programs, marking a win for immigrant rights groups who argued the policy was illegal and dangerous.

The ruling halted the Trump administration from pursuing the deportation of hundreds of thousands of migrants accepted into the United States, who now retain only minimal legal safeguards.
