New Facts: Medical Examiner Reports Cause of Death
On July 31, 2026, preliminary findings from the medical examiner determined that Sen. Lindsey Graham, 71, died from an aortic dissection, a tear in the inner layer of the aorta, the body's main artery.
He died on a Saturday night in July after a brief and sudden illness, hours after returning from a trip to Ukraine. His office initially announced his death without details.
An aortic dissection can cause catastrophic internal bleeding and collapse within minutes if not treated, which helps explain the sudden course described.
Graham was a four-term Republican senator from South Carolina and served as chairman of the Senate Budget Committee. He was known as a defense and foreign policy hawk and in later years became a close ally of Donald Trump.
Trump said he spoke with Graham on Saturday evening, shortly before the senator died. The medical examiner’s findings are preliminary.
