The longtime Republican senator died after a brief and sudden illness, according to a statement released by his office.
WASHINGTON — Republican Sen. Lindsey Graham of South Carolina, an influential foreign-policy voice and close ally of President Donald Trump, died Saturday after a brief and sudden illness, his office announced Sunday. He was 71.
Graham’s office did not identify the illness or release an official cause of death. His family thanked the public for its prayers and requested privacy, according to a statement posted on the senator’s social media account early Sunday.
The death ended a political career spanning more than three decades in state and federal office. Graham had represented South Carolina in the Senate since January 2003 and was seeking a fifth term in the November election. He previously served four terms in the U.S. House and two years in the South Carolina House of Representatives.
South Carolina Gov. Henry McMaster described Graham as an irreplaceable friend and a determined advocate for the state and the country. Other details about memorial services and funeral arrangements had not been announced Sunday morning.
Graham was born July 9, 1955, in Central, South Carolina, and grew up helping his parents run a restaurant, bar and pool hall. He was raised alongside his younger sister, Darline, and became her legal guardian after both of their parents died while he was attending college.
He earned undergraduate and law degrees from the University of South Carolina before joining the Air Force as a military lawyer. Graham later served in the South Carolina Air National Guard and the Air Force Reserve, retiring as a colonel in 2015 after more than three decades of military service.
Voters first elected Graham to the U.S. House in 1994. Eight years later, he won the Senate seat being vacated by Strom Thurmond, who had served South Carolina in the chamber for nearly half a century. Graham became the state’s senior senator and held prominent positions on committees overseeing the federal budget, the judiciary, defense spending and foreign relations.
Graham built a reputation as a defense hawk who argued for a strong American military presence overseas. He frequently supported aid to U.S. allies, including Israel and Ukraine, and advocated a hard line toward Russia and Iran. Shortly before his death, he had returned from a visit to Ukraine and was involved in efforts to advance new sanctions against Russia.
His relationships inside the Republican Party changed sharply during the Trump era. Graham challenged Trump for the party’s 2016 presidential nomination and criticized him during that campaign. After Trump won the presidency, however, Graham became one of his most visible congressional defenders and advisers, particularly on national security and judicial nominations.
The senator also sometimes worked with Democrats on immigration, military policy and judicial matters, though his later years in office were marked by increasingly partisan battles. He chaired the Senate Judiciary Committee during part of Trump’s first term and played a leading role in the confirmation of conservative federal judges.
Graham’s death creates a vacancy in South Carolina’s Senate delegation at a politically sensitive moment. State officials had not announced Sunday how or when the seat would be filled. Any appointment or election process will be governed by federal requirements and South Carolina law.
His office said no further details about his illness were immediately available. Additional information about the succession process and memorial arrangements was expected after state officials and Graham’s family completed their plans.
