Senator Lindsey Graham, R-S.C., suffered a fatal aortic dissection due to arteriosclerotic cardiovascular disease, according to reports on July 14, 2026. Tommy Tuberville, R-Ala., revealed that Graham called his scheduler expressing chest pains before emergency services were summoned.

Tuberville recounted that Graham said, “Listen, I'm having chest pains. You know, I need to do something.” When asked if he had called 911, Graham responded, “No, that's the reason I called you.” A former member of Tuberville’s staff, who was with Graham’s scheduler at the time, subsequently called 911. By the time emergency responders arrived, they had to knock down the door and were actively working on Graham.

Axios reported that in one of Graham’s final conversations, he mentioned feeling unwell but intended to wait until after his scheduled appearance on NBC’s "Meet the Press" to seek medical attention.

Senate Majority Leader John Thune, R-S.D., paid tribute to Graham, stating that the "halls of the Senate already feel empty without him."

Following Graham’s passing, a successor is slated to be sworn in on Tuesday after being appointed by the South Carolina Governor. During a ceremony in Columbia, South Carolina, Nordone said, "I think this is what Lindsey would have wanted, and I plan to honor him in this way."

Medical experts have explained that aortic dissection is a rare but serious condition often linked to high blood pressure and arterial plaque, emphasizing the importance of regular health check-ups.
