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 Supreme Court on Friday allowed the Trump administration to revoke the temporary legal status of more than 500,000 immigrants that was granted by the Biden administration, making them subject to deportation.

The decision lets the Trump administration halt, for now, a program that lets migrants from Cuba, Haiti, Nicaragua and Venezuela live and work in the U.S. for up to two years.

The administration had asked the court to allow it to end deportation protections for more than 500,000 people facing dire humanitarian crises in their home countries.

The Supreme Court on Friday allowed President Donald Trump’s administration to suspend a Biden-era humanitarian parole program that allowed half a million immigrants from Cuba, Haiti, Nicaragua, and Venezuela to temporarily live and work in the United States.

In the tariff case and others, courts are finding the president’s expansive view of executive authority clashes with decisions that limit its reach.

The Supreme Court has backed a multibillion-dollar oil railroad expansion in Utah in a ruling that scales back a key environmental law and could speed development projects around the country.
