The U.S. Supreme Court has acted in a series of cases involving challenges to executive orders signed by President Donald Trump and actions by his administration since he returned to office in January.

The emergency appeal asks the justices to halt a lower-court order keeping in place temporary legal status for more than 500,000 people from Cuba, Haiti, Nicaragua, and Venezuela.

President Donald Trump's administration is asking the Supreme Court to allow it to end humanitarian parole for hundreds of thousands of immigrants from four countries, setting them up for potential deportation.
