Hours before he died, Sen. Lindsey Graham (R-S.C.) brushed aside a warning to seek medical care and cracked a dark joke about all the foreign policy work he still had left to do. In a new account of the South Carolina Republican’s final evening, journalist Barak Ravid reported that Graham complained of feeling unwell shortly after a Saturday phone call with President Donald Trump — yet he insisted on waiting.
A source close to the 71-year-old senator described the exchange. When the person pressed Graham to get help right away, Graham said he would do so Sunday morning, after a scheduled appearance on NBC’s “Meet the Press.” Then he delivered a grimly ironic remark: “I can’t die now. I still need to do the Russia sanctions, get Iran sorted out and do Israeli-Saudi normalization.” He died several hours later.
A Fatal Aortic Tear
Graham’s office publicly confirmed his death early Sunday, describing what it initially called a “brief and sudden illness” at his Washington, D.C., home. The Medical Examiner of the District of Columbia later determined in a preliminary report that Graham died from an aortic rupture caused by hardened arteries — an aortic dissection due to arteriosclerotic cardiovascular disease. The dissection occurs when a tear forms in the body’s main artery that pumps blood away from the heart, and arteriosclerotic cardiovascular disease refers to the gradual weakening of the arteries. An official cause of death will be released once toxicological and microscopic testing is complete.
The senator had returned Friday from a trip to Ukraine, and his final days were consumed by the very issues he referenced in his joke. Graham spoke with Trump on Saturday evening, briefing the president on his Ukraine visit, and Trump told him he planned to order new military strikes on Iran after another incident involving commercial ships in the Strait of Hormuz, according to Ravid.
Trump offered his own recollection of the conversation during an appearance on “Meet the Press.” He said Graham called after returning from Ukraine and “sounded a little tired, but perfect.” Trump recounted that the senator was eager to move the Safeguard American Voter Eligibility (SAVE America) Act, telling him they were “all set” and that Graham “was pushing the SAVE America Act like crazy.” The president later reflected on the timing, saying it could have been Graham’s last call.
An Unfinished Sanctions Push
Graham’s remark about Russia sanctions was no throwaway line. In the final weeks of his life, he had been advancing a bipartisan sanctions package designed to ratchet up pressure on Russia, working alongside Democratic Sen. Richard Blumenthal of Connecticut. One day before his death, Graham told reporters in Kyiv that the White House had agreed to support the legislation. He said an agreement had been reached with the White House on a version the administration would support, and he pledged to press both Republican and Democratic leaders to find floor time for the package once he was back in Washington.
He framed the effort as leverage. Combining new technology to bolster Ukraine’s defense against ballistic missile attacks with tools to punish countries that prop up Russia, Graham argued, offered the strongest chance in his years of visiting Kyiv to force Russian President Vladimir Putin toward peace talks. His broader agenda also included a long-running push to broker normalization between Saudi Arabia and Israel.
A Scramble to Fill the Seat
Known for his hawkish foreign policy, Graham had traveled a striking arc, transforming from an outspoken Trump critic into one of the president’s closest allies in the Senate. His death left an immediate vacancy and set off a rapid succession.
At Trump’s suggestion, South Carolina Governor Henry McMaster (R) on Monday selected Graham’s younger sister, Darline Graham Nordone, to fill the seat through the end of the term, which is set to end in January 2027. Graham Nordone said her brother had always been there for her, and that stepping in was what he would have wanted. She said she planned to honor him in this way.
Graham’s sudden death prompted tributes from lawmakers in both parties. Sen. Amy Klobuchar (D-Minn.) praised his willingness to tackle difficult issues, saying he was ready to work on “gnarly issues” and to take on political risks for the right reasons.
Yet the loss also fueled a wave of misinformation. The senator’s death quickly sparked conspiracy theories across social media, with some users falsely claiming he had been assassinated and pointing fingers at foreign governments including Russia and Iran. The medical examiner’s findings, however, pointed to natural causes — the aortic tear that Graham, warned hours earlier, chose to ignore until a morning that never came.
