US Senator Lindsey Graham, close aide of Trump, dies after a ‘brief and sudden’ illness days after Iranian hardliners threatened to kill him

United States Senator Lindsey Graham passed away on Saturday, July 11, 2026, at the age of 71, following a brief and sudden illness at his Washington D.C. residence.⁠ The senior Republican lawmaker from South Carolina suffered chest pain and went into cardiac arrest shortly after returning from Kyiv, where he had concluded his tenth visit to Ukraine during the ongoing conflict. Emergency services responded to the home, and his office later confirmed the passing.

A brief statement said, “On the evening of Saturday, July 11, U.S. Senator Lindsey Graham passed away from a brief and sudden illness. Senator Graham’s family appreciates prayers at this time and asks for privacy during this incredibly difficult period.”

Senator Graham had met Ukrainian President Volodymyr Zelenskyy during the trip and discussed defence cooperation, including advancements in drone technology with Ukrainian manufacturers. He had long been one of the strongest voices in the US Congress supporting military aid to Kyiv and imposing tougher sanctions on Russia.

The news of his demise comes just days after Iranian hardliners openly threatened him with death. At the funeral of Supreme Leader Ayatollah Ali Khamenei in Tehran, posters displayed images of Senator Graham alongside other prominent figures including former President Donald Trump, with red targets marked over their faces. The accompanying text read: “Sooner or later, your heads will roll.”

Senator Graham had responded to the threat on social media on July 6, posting a photograph of the placard with the threat and writing, “At least they used a good photo of me. Judge me by my enemies.”

A native of South Carolina born in 1955, Senator Graham had earlier served in the US House of Representatives and maintained a high-profile role on key committees, including the Judiciary and Budget panels. A former critic of Donald Trump during the 2016 presidential campaign, Graham later became one of Trump’s most vocal supporters and a close ally within the Republican Party.

In Donald Trump’s second term, Lindsey Graham had become an influential member on foreign policy. He was also one of the Republicans who had advocated for the war against Iran, and was sceptical of the agreement signed between Iran and US.
