Aaron Burr Acquitted of Treason

Jurors quickly acquit Aaron Burr after Chief Justice John Marshall instructs them that the U.S. Constitution requires the testimony of at least two witnesses for a treason conviction (Article III, Section 3). Burr allegedly schemed to form a breakaway republic. He is known for killing Alexander Hamilton in a duel while serving as the nation's third vice president.
