The District of Columbia's Office of the Chief Medical Examiner has announced that Senator Lindsey Graham, a Republican, passed away due to an aortic dissection caused by atherosclerotic cardiovascular disease. This preliminary finding was released following his unexpected death on Saturday night.
Authorities emphasized that this diagnosis is not final, as further toxicological and microscopic analyses are required for conclusive certification.
An aortic dissection is a sudden medical emergency that occurs when the inner layer of the aorta—the main artery carrying blood from the heart to the rest of the body—tears, leading to a separation of its layers.
Graham was 71 years old and had celebrated his birthday just two days before his passing, on July 9.
Family and Presidential Reactions
His office described his death as the result of a "brief and sudden illness" and requested respect for his family's privacy during this difficult time, expressing gratitude for the prayers received.
Former President Donald Trump shared that he had spoken with Graham by phone hours before his death. At the time, Graham was returning from a trip to Ukraine and seemed well, albeit somewhat fatigued. "He was like family. It’s very hard," Trump remarked upon hearing the news.
During their final conversation, Graham reaffirmed his support for the SAVE America Act. In honor of the late senator, Trump ordered flags to be flown at half-staff nationwide until the following Saturday at six in the evening.
Graham's Legacy and Influence
Representing South Carolina in the Senate since 2003, Graham chaired the Budget and Judiciary Committees during Trump’s second term, becoming one of the president's most powerful allies in Congress.
On the international stage, Graham was a persistent voice on security and foreign policy. In his final weeks, he was working on a sanctions package against Moscow. His last known public engagement was his visit to Ukraine, where he met with President Volodymyr Zelensky, who praised him as a "true defender of liberty and the values that make our world safer."
Israeli Prime Minister Benjamin Netanyahu also expressed his condolences, stating, "Israel has lost one of its great friends. America has lost a great patriot. I have lost a dear friend."
Focus on Cuba and Future Senate Vacancy
In recent months, Graham had made Cuba's cause a personal priority. In March 2026, he appeared on Fox News wearing a "Free Cuba" cap, declaring that the dictatorship's "days are numbered." By May, he supported efforts to hold Raúl Castro criminally accountable for the 1996 downing of Brothers to the Rescue aircraft.
Graham's passing leaves a vacancy in the Senate that Republican Governor Henry McMaster of South Carolina is tasked with filling. According to state law, McMaster can appoint a temporary replacement until a special election is conducted.
Graham had been seeking a fifth term in the November 2026 elections. His absence poses a significant challenge to the already narrow Republican majority in the chamber.
