Is the president a king? The US supreme court thinks so. On Monday, in its very last ruling of the term, the chief justice, John Roberts, writing for the court’s six conservatives, held in Trump v United States that Donald Trump has “absolute immunity” from criminal prosecution for all acts that can be interpreted as part of the official course of his “core” duties, and “presumptive” immunity for all other official acts.

The move dramatically extends executive authority, insulates past and future presidents from prosecution for illegal or even treasonous actions they carry out while in office and renders the former president largely criminally immune for his role in the January 6 insurrection.

The court said that Trump cannot be charged for some of his “official” actions in the lead-up to the insurrection, including his attempts to pressure Mike Pence and his efforts to weaponize the justice department to force some states to reverse their election results. Much of Jack Smith’s criminal case against Trump has thereby been voided.
