Sen. Lindsey Graham (R-SC), who represented South Carolina in the Senate for more than two decades and was a stalwart supporter of Israel during his time in office, died on Saturday, his office announced. He was 71.

Graham, who served in the House of Representatives for more than a decade before being elected to the Senate in 2002, had recently returned from Ukraine, where he met with Ukrainian President Volodymyr Zelensky. Prior to Ukraine, he had been part of a bipartisan U.S. delegation in Ankara, Turkey, for the NATO summit.

NBC News reported that emergency personnel had responded on Saturday evening to a call regarding a cardiac arrest at Graham’s home on Capitol Hill.

A longtime advocate for Israel, Graham traveled to the country in the immediate aftermath of the Oct. 7, 2023, Hamas terror attacks, making at least 10 trips to the region since the onset of the Israel-Hamas war. He last traveled to Israel days before the outbreak of the Iran war in February 2026, during which he met with Israeli Prime Minister Benjamin Netanyahu.

Graham was openly critical of Iran and skeptical of Western engagement with the Islamic Republic. He was a vocal opponent of the 2015 Joint Comprehensive Plan of Action and favored military engagement to address the threats posed by the Islamic Republic. He defended the Trump administration’s recent negotiations with Tehran, but said in June that he thought those talks were “going to fail.”

The South Carolina Republican had been up for reelection in November after easily clearing the GOP field in the state’s primary last month. Graham’s death is expected to trigger a special primary in the state to determine who will replace him on the ballot.

The Republican lawmaker was swiftly eulogized by top Israeli political figures.

Israeli Prime Minister Benjamin Netanyahu said Israel had “lost one of its greatest friends.” Graham, Netanyahu said, “understood that the security of Israel and America are inseparable. He devoted his life to defending America, strengthening our alliance and standing up for the free world.”

Israeli President Isaac Herzog said in a statement that he was “shocked and heartbroken” to learn of Graham’s death, calling the senator a “dear friend” and a “great American patriot, a great friend of Israel.”

“Senator Graham was a beacon of moral clarity and a true leader of the U.S.-Israel partnership,” Herzog said. “We will never forget how he stood by the people of Israel in our most difficult moments, and we will remain eternally grateful for his sense of justice, truth, and loyalty.”

In a social media post, former Israeli Prime Minister Naftali Bennett, who is running in the current election, mourned Graham as one of the country’s “greatest friends,” who “stood with Israel through our darkest hours, with courage.”
