President Donald Trump has expounded an extraordinary vision of his authority over the past month, relying on the Supreme Court’s decision last year granting him immunity from criminal prosecution, as a blank check in his broader drive for power.

The court’s conservative majority may be receptive to the argument that presidents have unlimited power to remove leaders of independent agencies.

The first legal challenge to President Trump’s aggressive agenda is now heading to the Supreme Court after he asked the justices to remove a lower court order that blocked him from ousting a top government watchdog.

The Supreme Court could rule as early as this week on whether Special Counsel Hampton Dellinger should be reinstated and given access to his office, the first legal clash to reach the justices during this Trump administration over congressional protections for some federal officials.
