In 19th Century Washington, D.C., it was not unusual for Members of Congress to room together in boarding houses while Congress was in session. Many political deals were debated and decided in Washington’s boarding houses which were set up to appeal to a Congressman’s need for prepared meals and affordable housing. Buchanan, however, was a fairly wealthy man for his age and time period. The affordable housing that resulted from taking on a roommate wasn’t a necessity for Buchanan. It was a choice. And, instead of living with a variety of different colleagues over the years, Buchanan lived with one — Alabama Senator William Rufus DeVane King — for fifteen years.
The close relationship between Buchanan and King raised eyebrows even in their own time. Contemporaries referred to them as “Siamese twins”. Andrew Jackson called Buchanan and King “Aunt Fancy” and “Miss Nancy” respectively. President Polk’s law partner, Aaron Brown, went further, referring to King as “Mr. Buchanan’s wife”. The relationship between Buchanan and King was interrupted from time-to-time by each man’s foreign service (Buchanan as Minister to Russia during Jackson’s Presidency; King as Minister to France during Polk’s).
