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 order, which drew a sharp dissent from the three liberal justices, powerfully endorsed President Donald Trump’s authority over the federal bureaucracy.

The decision is the latest in which the court's conservative majority sided with the president's power to fire agency officials in violation of long-standing laws.
