Traditionally, the presidential oath of office is administered by the Chief Justice of the Supreme Court. At times, it has been administered by some other member of the federal judiciary.

Only two presidents, however, have been given the oath of office by an individual who was not a federal judge: George Washington and Calvin Coolidge.

Robert Livingston, Chancellor of State of New York, swore in George Washington as the nation's first president in 1789, and Calvin Coolidge was given the oath of office in 1923 by his father, a Notary Public.
