U.S. Senator Lindsey Graham (R-SC) died Saturday evening, July 11, 2026 [2], at his home in Washington, D.C. [3].
The death of the long-serving senator removes a prominent voice from the Republican leadership and creates a vacancy in the U.S. Senate for South Carolina.
A medical examiner said Graham died from an aortic dissection [1]. This condition occurs when a tear develops in the inner wall of the aorta, the main artery carrying blood from the heart to the rest of the body [1].
According to the medical examiner, the dissection was linked to the hardening of Graham's arteries [1]. Other reports indicated the rupture was brought on by chronic heart disease [4].
Graham was 71 years old [3]. His office previously described the event as a brief and unexpected illness [5].
The senator died in the capital city where he had served for years as a key figure in federal legislation, and judicial appointments. The medical examiner's findings confirm the physical cause of death following the unexpected nature of the illness reported by his staff [5].

The sudden death of Senator Graham creates an immediate political vacancy in South Carolina. Because aortic dissection is often a rapid and catastrophic event, the medical examiner's focus on chronic heart disease and arteriosclerosis provides necessary clinical context for a death that his office initially termed unexpected.
