Senator Darline Graham (R-SC) took the oath of office Tuesday, July 14, 2026 [1], in the U.S. Senate chamber in Washington, D.C. [4].

Graham fills the seat previously held by her older brother, Senator Lindsey Graham. The appointment ensures South Carolina maintains its full representation in the Senate following a sudden vacancy in the delegation.

The swearing-in ceremony follows the death of Senator Lindsey Graham, who died of an aortic dissection [5]. He was 71 [2] at the time of his death.

Graham's appointment marks a milestone for gender representation in the upper chamber. With her swearing-in, the number of women serving simultaneously in the Senate has reached 27 [3], a record high for the institution.
