Darline Graham Nordone was sworn in Tuesday to serve as South Carolina’s U.S. senator, filling the seat left vacant by the death of her older brother, Lindsey Graham. This marks her first time holding elected office.

Under South Carolina law, the governor appoints a replacement to serve the remainder of a senator’s term when a vacancy arises. Graham Nordone will serve until January 2027, the scheduled end of Lindsey Graham’s term. A special election will not be held; instead, voters will choose a senator for the next full term during the midterm elections on November 3.

Lindsey Graham, a Republican, had planned to run for re-election before his passing. Details about Graham Nordone’s political positions remain sparse, as she has not previously been involved in public office or widely discussed in the political arena.

Her appointment ensures South Carolina maintains its full representation in the Senate as the state prepares for this year’s election cycle.
