Senator Lindsey Graham, a senior Republican from South Carolina, died on the evening of July 11, 2026, at age 71 from an aortic dissection caused by cardiovascular disease [1, 2, 3, 4]. Emergency medical services responded to a call for chest pains and cardiac arrest at Graham's Capitol Hill residence around 8:30 p.m. that day, but he was declared dead following a brief and sudden illness [1, 5, 6, 7, 8, 9, 2].
Graham had served 24 years in the Senate since being first elected in 2002 and was seeking a fifth term. He recently won the June 9 Republican primary for South Carolina’s upcoming November midterm election [1, 10, 7, 2].
Known as a foreign policy hawk, Graham strongly advocated for U.S. military intervention abroad with firm support for Israel, Ukraine, and a hardline stance on Iran [1, 11, 9, 12]. Just days before his death, he returned from Kyiv, where he met Ukrainian President Volodymyr Zelenskyy [1, 11, 9, 2]. Zelenskyy called Graham "a true defender of freedom and the values that make our world safer" [1]. Israeli Prime Minister Benjamin Netanyahu said, "Israel has lost one of its greatest friends. America has lost a great patriot. I have lost a beloved friend" [9].
Former President Donald Trump, whom Graham had backed after an initial period of criticism, commented, "Senator Lindsey Graham, one of the greatest people and Senators I have ever known, is dead! He was always working, and was a true American Patriot. Lindsey will be greatly missed!!!" [8]. South Carolina Governor Henry McMaster said, "Lindsey Graham is irreplaceable. The fiercest of fighters for South Carolina and America – and a loyal and steadfast friend" [11].
With Graham's passing, Governor McMaster has the authority to appoint a temporary replacement senator until a special election can be held [1, 9].
