Aaron Burr engaged a Secretary of Treasury in a duel.
== Legacy ==Although Burr is often remembered primarily for his duel with Hamilton, his establishment of guides and rules for the first impeachment trial set a high bar for behavior and procedures in the Senate chamber, many of which are followed today
In the spring of 1776, Burr's stepbrother Matthias Ogden helped him to secure a position with George Washington's staff in Manhattan, but he quit on June 26 to be on the battlefield
