In a separate case in a different jurisdiction, Mr. Trump has raised a more exotic species of double jeopardy. He does so in respect of his January 6 trial, where the 45th president argues that the Senate’s acquittal of him on charges of insurrection handed up in an impeachment precludes his further prosecution on criminal charges.

Mr. Trump, who so far has failed to persuade a court to vindicate his position, points to the Constitution’s Impeachment Judgment clause, which ordains that the “Party convicted shall nevertheless be liable and subject to Indictment, Trial, Judgment and Punishment, according to Law.” Mr. Trump wasn’t a “party convicted” but a “party acquitted” of incitement to insurrection.
