Preliminary findings from the Washington, D.C. medical examiner's office released on Sunday indicate that U.S. Senator Lindsey Graham died from a ruptured aorta caused by chronic heart disease. The 71-year-old South Carolina Republican succumbed to an aortic dissection resulting from arteriosclerotic cardiovascular disease, a condition involving a sudden tear in the body's main artery. Medical experts note that this emergency predominantly affects older men with a history of arterial plaque buildup.
Official death certificate pending further tests
While the initial findings point definitively to cardiovascular failure, the medical examiner's office stated that the official death certificate will remain pending until standard toxicological and microscopic testing are completed over the coming weeks. This means the exact cause could be refined or confirmed after additional analysis.
Emergency personnel were dispatched to Graham's Capitol Hill residence at approximately 8:30 p.m. on Saturday following a 911 call reporting severe chest pains. First responders performed cardiopulmonary resuscitation (CPR) at the scene before rushing the veteran lawmaker to George Washington University Hospital, where he was pronounced dead.
Timeline of events before collapse
The medical emergency occurred just hours after Graham returned to Washington from an official diplomatic trip to Kyiv, Ukraine. Shortly before his collapse, around 7:00 p.m., the senator spoke via telephone with former President Donald Trump. Trump shared during an interview on NBC News' Meet the Press, where Graham had been scheduled to appear Sunday morning: "He sounded a little tired, but perfect, but a little bit tired. He sounded great actually. He was like a member of the family to me. It's very tough, actually."
Graham's family has a documented history of cardiovascular issues; his father also passed away from a sudden heart attack in his late 60s. This genetic predisposition may have contributed to the senator's own health crisis.
End of a consequential career
Graham's passing brings an abrupt end to a consequential two-decade career in the U.S. Senate, where he was widely known as a leading voice on foreign policy and national defense. He consistently advocated for robust American military presence abroad, maintaining strong stances on interventions in the Middle East and championing recent legislative efforts to fund Ukrainian defense forces. His absence will be felt in ongoing debates over international security and defense spending.
Though Graham famously clashed with Trump during the 2016 Republican presidential primaries, most notably defending the late Senator John McCain, the two eventually mended their relationship. Graham subsequently transitioned into one of the administration's most trusted legislative confidants and a pivotal strategist on Capitol Hill. His death has prompted reactions from colleagues across the political spectrum, highlighting his influence on both domestic and foreign policy.
