Lindsey Graham, the Republican senator from South Carolina and one of President Donald Trump’s closest allies, has died at the age of 71. His office announced that Graham passed away following a brief and sudden illness. However, no further details regarding the exact cause of his death have been released.

Graham served in the U.S. Senate since 2003 and, over the past two decades, became one of the Republican Party’s most influential figures, particularly in the field of foreign policy. He was a strong advocate for increasing pressure on the Islamic Republic of Iran, providing unconditional support for Israel, and expanding U.S. military cooperation with its allies. He also played a significant role in approving funding related to Israel’s Iron Dome missile defense system and supported sanctions against Iran.

Following news of his death, President Donald Trump issued a statement describing Graham as “one of the greatest senators and a true American patriot,” adding that his passing is a great loss for the United States.

Israeli Prime Minister Benjamin Netanyahu also expressed his condolences, calling Graham “one of Israel’s greatest friends.” He said, “Israel has lost one of its closest supporters, and I have lost a dear friend.”

Graham’s death has prompted widespread reactions across political circles in the United States and around the world. Many Republican leaders have praised him as an influential figure in shaping U.S. foreign policy, while his critics have faulted him for supporting military interventions and maintaining hardline positions toward several countries.
