The court’s action essentially extended an order Chief Justice John Roberts issued in April that had the effect of removing two board members who Trump fired from agencies that deal with labor issues, including one with a key role for federal workers as Trump aims to drastically downsize the workforce.

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

The Supreme Court ruled Thursday in favor of President Donald Trump's firing of two Democratic board members of independent oversight agencies as litigation over their removal continues.
