Following her husband's resignation as vice president and election to the United States Senate in 1832, Mrs. Calhoun returned to Fort Hill, resuming her former status as a plantation mistress, leaving the role of Second Lady of the United States vacant until 1841 because both of her husband's two immediate successors as vice president, Martin Van Buren and Richard Mentor Johnson, were unmarried during their time in office.
