Darline Graham Nordone was officially sworn into the U.S. Senate on Tuesday, stepping into the seat once held by her late brother, Lindsey Graham, and pledging to continue the work he championed on behalf of South Carolina and the nation.

Nordone took the oath of office just one day after being appointed by South Carolina Gov. Henry McMaster, who selected her Monday to fill the vacancy created by Graham’s unexpected death two days earlier. Senate President Pro Tempore Chuck Grassley of Iowa administered the oath during Tuesday’s ceremony.

At 62, Nordone becomes the first woman ever to represent South Carolina in the U.S. Senate. Her temporary appointment will last until Jan. 3, 2027, when the winner of the special election officially takes office.

Speaking after her appointment was announced Monday, Nordone reflected on the opportunity before her.

“It is such a privilege to get to finish some of his important work, and I promise to work hard over the next several months to support the president and carry forward the efforts of my brother on behalf of the citizens of South Carolina and the United States,” Nordone said at a press conference Monday after her appointment was announced.

Although she has never previously served in elected office, Gov. McMaster’s office emphasized that Nordone brings decades of experience in public service.

Since 2019, she has led the South Carolina Commission for the Blind as commissioner, where, according to the governor’s office, she “has worked to expand opportunities for South Carolinians who are blind or have low vision to achieve employment and independence.”

State employment records identify Nordone as the agency’s chief executive, with an annual salary of approximately $138,000. As a U.S. senator, her prorated annual salary will be about $174,000.

Before taking over the Commission for the Blind, Nordone spent nearly three decades serving in various public-sector positions, including roles with Clemson University, the South Carolina Department of Employment and Workforce, and the South Carolina Department of Vocational Rehabilitation.

McMaster’s office also highlighted her additional leadership positions, stating, “In addition to her full-time role as SCCB Commissioner, Ms. Graham currently serves on the South Carolina State Workforce Development Board and is president-elect of the National Council of State Agencies for the Blind,” the McMaster statement continued.

Nordone earned a bachelor’s degree from the College of Charleston and a master’s degree in rehabilitation counseling. She is also a Certified Public Manager.

Before McMaster made his decision, President Donald Trump and several South Carolina Republican lawmakers publicly endorsed Nordone as the best choice to temporarily succeed her brother.

“I recommended, to Governor Henry McMaster, Lindsey Graham’s wonderful sister, Darline, to serve as interim Senator from the Great State of South Carolina,” Trump wrote on Truth Social. “This would be a fabulous tribute to Lindsey, who loved her dearly!”

Her appointment follows a well-established pattern in American politics, where close relatives have occasionally been chosen to fill congressional vacancies after the deaths of family members.

According to the Center for American Women and Politics at Rutgers University, eight widows have been appointed to replace their late husbands in the U.S. Senate, while the House of Representatives has seen 39 similar successions.

One of the most notable examples occurred in 2001, when Jean Carnahan was appointed to Missouri’s Senate seat after her husband, Democratic Gov. Mel Carnahan, won election posthumously three weeks after he was killed in a plane crash.

Jean Carnahan later lost the seat in a 2002 special election to Republican Jim Talent.

South Carolina Republicans are scheduled to hold a special primary on Aug. 11 to determine the party’s nominee for the November election to permanently fill Graham’s Senate seat.

Lindsey Graham, who never married and had no children, died suddenly Saturday evening after suffering a tear in his aorta. He was 71.

Preliminary findings from the Washington, D.C., medical examiner concluded that the fatal rupture resulted from chronic heart disease.
