"Under our constitutional structure of separated powers, the nature of presidential power entitles a former president to absolute immunity from criminal prosecution for actions within his conclusive and preclusive constitutional authority,” Chief Justice John Roberts wrote for the court. “And he is entitled to at least presumptive immunity from prosecution for all his official acts. There is no immunity for unofficial acts.” Justice Sonia Sotomayor wrote, “In every use of official power, the President is now a king above the law.”
