South Carolina Governor Henry McMaster has officially named Darline Graham Nordone, the sister of the late Senator Lindsey Graham, to fill his U.S. Senate seat on an interim basis. The announcement came at a 4 p.m. press conference, following hours of speculation after news of the appointment spread rapidly online.
Graham passed away after suffering a cardiac event on Saturday evening. McMaster moved quickly, reaching out to Nordone early Sunday morning to ask her to serve. He then brought the idea to President Donald Trump, who gave it his full backing.
Nordone accepted the role, thanking the governor and the people of South Carolina for what she called the “honor and privilege” of continuing her brother’s work. She pledged to support President Trump’s agenda going forward.
Trump had already made his preference publicly known earlier in the day. I recommended, to Governor Henry McMaster, Lindsey Graham’s wonderful sister, Darline, to serve as interim Senator from the Great State of South Carolina,” the president posted on Truth Social. “This would be a fabulous tribute to Lindsey, who loved her dearly.”
As originally reported, Senate Majority Leader John Thune signaled his support for the pick, telling reporters it would “make a lot of sense.”
Under South Carolina law, the governor holds the authority to appoint someone to fill a Senate vacancy until a special election can be held. Nordone’s appointment allows her to serve the remainder of Graham’s term, which runs through January 2027.
Nordone, also known as Darline Graham, is Graham’s only sibling. She maintained a relatively private life compared to her brother, but Graham referenced her often in personal terms, particularly when reflecting on family after the deaths of their parents. Graham, who never married and had no children, frequently described her as a central part of his personal support system.
Her appointment represents a direct familial continuation in a Senate seat Graham held since 2003.
Because Graham had already secured the Republican nomination for the 2026 general election before his death, state election rules require a special primary to select a new Republican nominee. That primary is currently scheduled for August 11, 2026, with the general election to follow in November. The winner will serve the full six-year term beginning in January 2027.
Several names are already circulating as potential candidates for that race. Lieutenant Governor Pamela Evette, who narrowly lost a recent gubernatorial runoff against Attorney General Alan Wilson, is among those being discussed. U.S. Representatives Ralph Norman and Nancy Mace, both of whom also ran in that gubernatorial primary, have been mentioned as well.
For now, the focus remains on Nordone stepping into one of the most prominent political roles in the state, carrying on her brother’s legacy.
