"This case presents a fundamental question at the heart of our democracy: whether a former President is absolutely immune from federal prosecution for crimes committed while in office or is constitutionally protected from federal prosecution when he has been impeached but not convicted before the criminal proceedings begin. The district court rejected respondent's claims, correctly recognizing that former Presidents are not above the law and are accountable for their violations of federal criminal law while in office. App., in- fra, 7a-38a, 46a-53a. Respondent's appeal of the ruling rejecting his immunity and related claims, however, suspends the trial of the charges against him, scheduled to begin on March 4, 2024. It is of imperative public importance that respondent's claims of immunity be resolved by this Court and that respondent's trial proceed as promptly as possible if his claim of immunity is rejected. Respondent's claims are profoundly mistaken, as the district court held. But only this Court can definitively resolve them. The Court should grant a writ of certiorari before judgment to ensure that it can provide the expeditious resolution that this case warrants, just as it did in United States v. Nixon, 418 U.S. 683, 686-687 (1974)."
