Lindsey Graham’s sister, Darline Graham Nordone, has been named as her late brother’s temporary replacement in the U.S. Senate after his unexpected death over the weekend.

South Carolina Gov. Henry McMaster announced at a news conference at the Statehouse on Monday (July 13, 2026) that Ms. Nordone would serve the remaining months on Graham’s current term, which expires in January. Senate Majority Leader John Thune said afterward that she will be sworn in Tuesday (July 14, 2026) afternoon.

Ms. Nordone will be the first woman to represent the State in the Senate.

“It is such an honor,” she said, as dozens of Graham staffers and campaign advisers stood behind her, some with eyes glassy from welling tears. “Lindsey has always been there for me. And now, I will be there for him.”

Graham died on Saturday (July 11, 2026) night at age 71. He never married or had a family of his own, but Ms. Nordone was often by her brother’s side for the political touch points of his career, speaking at events and appearing in some of his campaign ads.

After their parents died at a young age, Graham was left to raise his sister, for whom he later became legal guardian. They were very close, and she was there as he filed reelection paperwork earlier this year, along with her children and grandchildren.

“To Lindsey, I miss you more than I can even put into words,” Ms. Nordone said, emotion rising in her voice. “But I’m going to do this. I got it.”

Introducing Ms. Nordone, Mr. McMaster said the two had spoken in “in the wee hours of Sunday morning” after Graham’s death, and he asked her to serve.

“I had wondered what you would say, and I was humbled by your quickness to see the duty that you had to serve,” Mr. McMaster said. He added that President Donald Trump “thought it was a great idea” when he later told him of his pick. Mr. Trump announced his support for Ms. Nardone to fill the seat earlier Monday (July 13, 2026).

Ms. Nordone has worked as an optician and at various state agencies, including the South Carolina Commission for the Blind and the Department of Employment and Workforce. She lives in Lexington, is a graduate of the College of Charleston and has a master’s degree in rehabilitation counseling.

A special election will be held next month to pick a new Republican nominee in the general election for Graham’s seat. He had been seeking a fifth term this year.

The rare open Senate seat has ignited a scramble among South Carolina’s most ambitious conservatives, who have been eager to climb the political ladder.

Republicans just finished a sprawling and bruising contest to figure out their nominee for succeeding Mr. McMaster, who is wrapping up his second term. State Attorney General Alan Wilson won the nomination, overcoming a field that included Lt. Gov. Pamela Evette, Rep. Nancy Mace and Ralph Norman — all of whom are now eyeing Graham’s seat following his death over the weekend.

According to South Carolina law, a one-week filing period for a special primary election begins on the second Tuesday (July 14, 2026) after the candidate’s death, or July 21.

The special primary election would be held on the second Tuesday (July 14, 2026) after that filing period closes, or Aug. 11. Any necessary runoff would follow two weeks after that, or Aug. 25.

From that point, the new nominee would have just over two months to campaign for the general election on Nov. 3.

All of this is problematic according to federal law, which requires military and overseas ballots to go out 45 days before any federal election. For the special election primary, that would have been June 27. Federal Election Commission officials didn’t immediately return a message seeking clarity about the process.

Graham died on Saturday (July 11, 2026) night, and a preliminary medical examiner report said he suffered a tear in his aorta, known as an aortic dissection.

In the hours after Graham’s death was announced, South Carolina’s Republican circles were already swirling with rumors about possible replacements.

Ms. Evette, who has served nearly eight years alongside Mr. McMaster and received his endorsement in the governor’s race, is one possibility. She lost the June 23 runoff to Wilson.

Ms. Mace and Mr. Norman could run in the special primary as well. Neither of them are running for reelection to their House seats.

But another Republican from the state, Rep. Russell Fry, could be a possibility. The two-term lawmaker represents the growing area around Myrtle Beach, and he’s been a top Trump ally.

Businessman Mark Lynch, whom Graham defeated in the primary, may jump into the race. So could Mark Sanford, the State’s former Governor who served two separate stints in the House.

Treasury Secretary Scott Bessent, who lived in South Carolina before joining the Trump administration, has fielded calls about potentially replacing Graham but doesn’t have interest in the role and enjoys working for the president, according to a person who insisted on anonymity to describe private conversations.

No Democrat has won a Senate seat in South Carolina in decades, and Republicans in recent history typically take statewide seats by double digits. When Graham last ran in 2020, he defeated his Democratic opponent, Jaime Harrison, by a 10 percentage point margin.

So while history suggests that Graham was en route to a fifth term, Republicans are carefully surveying the landscape.

Charleston pediatrician Annie Andrews won the Democratic nomination last month and has raised more than $8 million in the race, and she had just under $3 million cash on hand at the end of May, according to federal filings. Graham had taken in $6 million, with just over $4 million on hand.

In a statement Sunday(July 12, 2026), Ms. Andrews called on South Carolinians to join her “in setting partisanship aside and offering gratitude” to Graham for his service.

Mr. Harrison, noting that he and Graham “had our share of political disagreements,” wrote on social media that he “always appreciated that even in our fiercest political battles, we could still share a conversation, a laugh, and a mutual respect for South Carolina and the institutions we were both privileged to serve.”
