WASHINGTON (AP) — The U.S. Supreme Court’s decision Friday limiting federal judges from issuing nationwide injunctions threatens to upend numerous lawsuits that have led to orders blocking Trump administration policies.

After months of tension between President Donald Trump and the Supreme Court, the country’s high court ended its term by delivering its biggest win for Trump in his second administration, deciding to decrease the power of lower courts while increasing the president’s own.

If President Donald Trump has wielded his executive power like a Mack Truck over the last months, plowing ahead with a velocity unseen in his recent predecessors, his win at the Supreme Court on Friday could act as high-octane fuel in his tank.
