The Supreme Court on Friday dashed President Donald Trump’s plan to immediately fire the head of an independent agency that investigates whistleblower claims, allowing Hampton Dellinger to remain in the job through at least the middle of next week.

The Trump administration fired Hampton Dellinger, head of the Office of Special Counsel, who sued to overturn the decision.

The Supreme Court stiffed President Trump in his administration’s first high court appeal by punting Friday on a request to greenlight the firing of the head of a whistleblower protection office.
