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.

The U.S. Supreme Court has allowed presidential power to steadily expand in recent decades. Now the court may review Trump administration efforts to expand executive branch authority.

The case involves major constitutional questions about presidential power—but its unusual posture could make it a dud.
