Late U.S.Senator Lindsey Graham (R-SC) died after suffering an aortic dissection caused by arteriosclerotic cardiovascular disease, according to a report from the District of Columbia Medical Examiner's Office.

The findings, released by Graham's office on July 12, 2026, indicate that the fatal tear in Graham's aorta was linked to fatty plaques restricting blood flow.

While the official death certificate remains pending until toxicological and microscopic tests are completed, the medical examiner's preliminary report provides critical insight into the circumstances of his passing.

Graham, a prominent Republican senator known for his close ties to former President Donald Trump, died late Saturday night after being rushed from his Washington, D.C., home to George Washington University Hospital.

The report highlights the complex interplay between chronic cardiovascular conditions and acute medical emergencies, underscoring the importance of early detection and management of such diseases.His death has sparked discussions about the health risks faced by aging politicians and the broader implications for public health policy.

The case also raises questions about the transparency of medical information in high-profile political figures, as Graham's office emphasized that the final determination will be made once all tests are complete.
