On October 10, 1973, Spiro Agnew, serving under President Nixon, became the
second Vice President to resign the office. He pled no contest to criminal charges
of tax evasion after resigning. As a result of his no contest plea, the State of
Maryland later disbarred Agnew, calling him "morally obtuse". In 1832, Vice
President John C. Calhoun, while serving under Andrew Jackson, resigned
the office to take a seat in the U.S. Senate.
