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 court’s order indicated that it may return to the issue as soon as next week, when a trial judge’s temporary restraining order is set to expire.

The Supreme Court has temporarily kept on the job the head of the federal agency that protects government whistleblowers.
