The Supreme Court on Friday declined to fast-track a legal challenge to President Donald Trump 's tariffs, rejecting a motion to expedite the case and delaying consideration despite pressure from affected companies.

In a separate and broader challenge, the Court of International Trade also ruled against the administration’s tariffs program. A different appeals court, the Federal Circuit, is set to hear arguments in that case next month. Both lower court rulings have been paused, allowing Mr. Trump to press forward with his tariffs.
