Aaron Burr is a truly fascinating character from America's past. He served during the Revolutionary War under Benedict Arnold, and his valor led him to be part of George Washington's staff. He was often the center of controversy including being a critic of Washington's leadership and possibly thwarting a romance between Alexander Hamilton and the future Mrs. Dolley Madison. He became the third Vice President under Thomas Jefferson. He was not asked back to run for a second term. Then in 1804, he killed Alexander Hamilton in a duel. While he was charged with murder, he was never tried and actually completed his Vice Presidential term in Washington, D.C. On January 22, 1807, President Thomas Jefferson uncovered a plot by Aaron Burr to form a new republic in the Southwest. However, one clause in the Constitution requires two witnesses to convict a person of treason so he was eventually acquitted.
