President Thomas Jefferson receives a subpoena to testify in the treason trial of his former vice president, Aaron Burr, on June 13, 1807. In the subpoena, Burr asked Jefferson to produce documents that might exonerate him.
Burr had already been politically and socially disgraced by killing former Treasury Secretary and Revolutionary-era hero Alexander Hamilton in a duel in 1804. After killing Hamilton, Burr, still Jefferson’s vice president, went into hiding. Burr then concocted a seditious plan to enlist the help of Britain and Spain to create a separate nation in the southwestern reaches of the American continent, including parts of Mexico, over which Burr would rule. The outrageous plan failed miserably when one of Burr’s co-conspirators, General James Wilkinson, betrayed Burr and alerted Jefferson to the plot. Burr was hunted down and arrested in 1806 and indicted for treason.
