Buchanan had a close and intimate relationship with William Rufus King, an Alabamian politician who briefly served as vice president under Franklin Pierce. Buchanan and King lived together in a Washington boardinghouse for many years, from 1834 until King's departure for France in 1844. King referred to the relationship as a "communion",[101] and the two attended social functions together. Contemporaries also noted the closeness. Andrew Jackson called King "Miss Nancy" and prominent Democrat Aaron V. Brown referred to King as Buchanan's "better half", "wife" and "Aunt Fancy" (the last being a 19th-century euphemism for an effeminate man).
