What killed Lindsey Graham? Early findings on the sudden death of Iran critic

Senator Lindsey Graham has reportedly died at the age of 71, according to a statement from his Senate office. Preliminary medical findings indicate that Graham suffered a fatal aortic dissection linked to underlying heart disease, although a final death certificate will be issued after toxicology testing and additional medical examinations. The longtime South Carolina Republican served nearly three decades in Congress and was widely recognized as one of Washington's leading foreign policy voices, a strong supporter of Ukraine, and a prominent advocate of a hardline approach toward Iran. His death came only hours after returning from a visit to Kyiv, where he met with Ukrainian President Volodymyr Zelenskyy and other senior officials.
