WASHINGTON (AP) — A month into President Donald Trump ‘s second term, lawyers for the Republican administration seem intent on provoking a legal fight to overturn a 90-year-old Supreme Court decision known as Humphrey’s Executor that has been critical to the development of the modern U.S. government.

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.

Donald Trump is already testing his sweeping assertion of presidential power with the US Supreme Court, which just a month into his new term is poised to say whether he can fire the head of a federal whistleblower agency.

The Supreme Court should reject an emergency appeal from the Trump administration asking for quick action to allow the firing of the head of the federal agency that protects whistleblowers.

President Trump’s Justice Department told the Supreme Court Wednesday that a district court shouldn’t be able to issue a temporary restraining order to upend his agenda — like removing the head of a whistleblower protection agency — especially in the first days of his administration.
