WASHINGTON — Authorities are investigating the circumstances surrounding the sudden death of U.S. Senator Lindsey Graham, while officials said preliminary medical findings indicate no evidence of foul play and point to a natural medical emergency as the likely cause.
The District of Columbia Office of the Chief Medical Examiner said a preliminary examination found that Graham, 71, died from an aortic dissection caused by arteriosclerotic cardiovascular disease. Officials said the death certificate will remain pending until toxicological and microscopic testing is completed and the manner of death is formally certified.
The Metropolitan Police Department is conducting a standard death investigation, with the Federal Bureau of Investigation providing assistance to local authorities. Law enforcement officials have not announced any evidence suggesting criminal activity and have cautioned against speculation while the inquiry remains active.
According to statements released by Graham's office, the South Carolina Republican died Saturday evening following what was described as a "brief and sudden illness." His family requested privacy as officials complete the medical examination.
Emergency responders were dispatched to Graham's Washington residence after reports of a medical emergency. Public reports citing emergency communications said responders treated the senator before he was transported to a hospital, where he was pronounced dead. Authorities have not released additional operational details beyond the ongoing investigation.
The senator had recently returned from a visit to Ukraine and had been expected to appear on a Sunday television program before his death. His office had not publicly disclosed any serious health concerns before the incident.
Graham served in the U.S. Senate since 2003 after representing South Carolina in the House of Representatives. A leading Republican voice on foreign policy and national security issues, he also chaired the Senate Budget Committee and served on several influential committees. His death leaves a vacancy that South Carolina's governor is expected to fill temporarily under state law pending a special election.
Officials have urged the public to rely on verified information as the investigation continues. The Chief Medical Examiner's office said the final cause and manner of death will be confirmed after laboratory testing is complete, while federal and local authorities have not indicated any change to their assessment that there is currently no evidence of foul play.
