Lindsey Graham, the longtime Republican senator from South Carolina who never married and had no wife, died on July 12, 2026, at age 71 following a brief illness. His sister, Darline Graham, was appointed by South Carolina Governor Henry McMaster on July 13 to complete his term, becoming the first woman to represent the state in the U.S. Senate.
Graham’s office said the preliminary cause of death was aortic dissection due to arteriosclerotic cardiovascular disease, a rupture of the aorta caused by hardening of the arteries. Emergency personnel responded to a call for cardiac arrest at his Capitol Hill home on Saturday night, according to police scanner audio. A top staffer told NBC News there was no indication Graham had been feeling unwell before his death.
Graham had been a prominent figure in the Senate since his election in 2002, serving as a close ally of President Donald Trump and a leading voice on defense and foreign policy. He was chairman of the Senate Budget Committee and had been seeking a fifth six-year term in the November 2026 election. Trump, who spoke with Graham on Saturday night hours before his death, called him “one of the greatest people and Senators I have ever known” and a “true American Patriot.”
Graham’s personal life remained private throughout his decades in public office. He never married and had no children, focusing his career on military service and legislative work. He served 33 years in the U.S. Air Force, Air Force Reserve, and South Carolina Air National Guard, retiring at the rank of colonel in 2015 while holding his Senate seat. Before winning the Senate seat previously held by Strom Thurmond, Graham served in the U.S. House of Representatives from 1995 to 2003.
Sister Takes Over Senate Seat
Darline Graham, 62, was sworn in as senator after her appointment, making history as South Carolina’s first female U.S. senator. According to Governor McMaster’s office, she has dedicated nearly 30 years to public service in South Carolina. Since 2019, she has served as Commissioner of the South Carolina Commission for the Blind, where she works to expand opportunities for blind and low-vision South Carolinians to achieve employment and independence.
Before her role at the Commission for the Blind, Darline Graham held positions with Clemson University, the South Carolina Department of Employment and Workforce, and the South Carolina Department of Vocational Rehabilitation. She earned a bachelor’s degree from the College of Charleston, a master’s degree in rehabilitation counseling, and is a Certified Public Manager. She also serves on the South Carolina State Workforce Development Board and is president-elect of the National Council of State Agencies for the Blind.
Under South Carolina law, Darline Graham will serve until January 3, 2027, when the new Congress convenes following the November 2026 general election. The state Republican Party held a special primary election in August 2026 to nominate a replacement candidate for the general election ballot. On July 20, Darline Graham announced she would run for a full Senate term, saying she was not “just a placeholder to finish her brother’s term.” The appointment marks a rare instance of a family member filling a U.S. Senate vacancy through gubernatorial appointment, a practice that has occurred multiple times throughout American history but remains uncommon.
