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.

A circuit court judge criticized the Supreme Court after it blocked the Trump administration's attempts to deport Venezuelan migrants.

The case raises fundamental questions about the power and transparency of an entity that has slashed agency budgets and government employees with unusual speed and that has inspired a wave of federal lawsuits against the Trump administration.
