Senator Lindsey Graham of South Carolina, a leading Republican voice on defense and foreign policy who evolved into one of Donald Trump’s closest allies, died on July 11, 2026, at age 71.
Graham died at George Washington University Hospital in Washington, D.C., after a brief and sudden illness, according to his office. The Washington, D.C., Medical Examiner’s Office determined that he died from an aortic dissection due to arteriosclerotic cardiovascular disease, a tear in the inner wall of the aorta related to hardening of the arteries.
The senator’s death came just hours after he returned from a trip to Ukraine, where he had traveled to assess the nation’s defense needs. He was scheduled to appear on television Sunday morning before his death became public Saturday night.
Over the course of his three decades in Congress, Graham became one of the most influential voices shaping U.S. foreign policy, according to NPR. A former member of the U.S. Air Force Legal Corps, he entered the House in 1995 and moved to the Senate in 2003, where he served for more than two decades. Graham championed a robust American military presence overseas and fierce defense of Ukraine and Israel, establishing himself as one of the last neoconservative hawks in the Republican Party.
Graham’s relationship with Trump shifted dramatically over time. He ran for the Republican presidential nomination in 2016 as a vocal Trump opponent, but later became one of the president’s closest allies and most loyal defenders. This alliance bridged Trump’s “America First” foreign policy with Graham’s more interventionist worldview.
President Trump led tributes to Graham, describing him as a “true American patriot” and a leading Republican voice on defense. Trump recommended that South Carolina Governor Henry McMaster appoint Graham’s sister, Darline Graham Nordone, to fill the vacancy, calling it “a fabulous tribute to Lindsey.”
McMaster announced on July 13 that he was appointing Darline Graham to serve as the temporary interim senator for the remainder of her brother’s term. She was sworn in on July 14, becoming just the 12th family member appointed to the U.S. Senate. The appointment is temporary; South Carolina law calls for a special Republican primary election in mid-August to determine who will replace Graham on the November general election ballot. Graham had won the Republican primary in June with 56.8% of the vote and was running for his fifth Senate term.
