Washington (Somalia Today) — The sudden death of US Senator Lindsey Graham, hours after he returned from Ukraine, has fuelled speculation about possible Russian involvement, although authorities have presented no evidence of foul play.
Graham, a South Carolina Republican and one of President Donald Trump’s closest allies in Congress, died in Washington on Saturday evening after what his office described as a “brief and sudden illness”.
“Senator Graham’s family appreciates prayers at this time and asks for privacy during this incredibly difficult period,” his office said in a statement released on Sunday.
Graham was 71.
Emergency crews responded to a reported cardiac arrest at his Capitol Hill home, according to US media reports citing emergency dispatch communications.
The District of Columbia’s Office of the Chief Medical Examiner later said preliminary findings showed that Graham suffered an aortic dissection caused by arteriosclerotic cardiovascular disease.
An aortic dissection occurs when a tear develops in the inner wall of the aorta, the body’s largest artery, allowing blood to force its way between the layers of the artery wall.
The medical examiner stressed that the finding remained preliminary. Graham’s death certificate remains pending while officials complete toxicology and microscopic examinations.
Senator Tim Scott of South Carolina had earlier said Graham appeared to have suffered a heart attack.
The preliminary medical finding offered the first official explanation for his sudden death.
However, the timing of his death, shortly after his 10th visit to Ukraine since Russia launched its full-scale invasion in 2022, had already prompted theories that a foreign government may have targeted him.
FBI Director Kash Patel said the bureau was helping local authorities and had made all necessary resources available.
He did not say the FBI had opened a criminal investigation, mention foul play or identify Russia or any other country as a suspect.
Online speculation
One of the strongest allegations came from Igor Eidman, an exiled Russian sociologist and Kremlin critic, who claimed there was a “very high probability” that Russian intelligence had killed Graham.
Eidman suggested that someone could have exposed the senator to a delayed-action poison during his visit to Ukraine.
However, he offered no intelligence assessment, witness testimony, medical evidence or other independently verifiable material to support the claim.
Conservative activist Laura Loomer also called for an investigation into possible Russian or Iranian involvement.
MAGA podcaster Clint Russell told his followers there was “a decent chance” Moscow was responsible, helping the theory spread across social media despite the lack of evidence.
Other accounts claimed Russian forces had destroyed the Ukrainian drone-production facility Graham visited and struck a Kyiv hotel where he was allegedly staying.
But the timeline accompanying those claims conflicts with the confirmed account of Graham’s movements.
He returned safely to Washington and spoke to Trump by telephone after leaving Ukraine. Independent sources have also not confirmed the alleged destruction of the facility he toured.
Trump said Graham sounded slightly tired after the journey but otherwise appeared normal during what may have been their final conversation.
The preliminary findings point to a sudden cardiovascular emergency, although the medical examiner has not yet issued a final death certificate.
Final Kyiv visit
Graham visited Kyiv on Friday and met Ukrainian President Volodymyr Zelenskyy to discuss the country’s urgent air-defence needs, efforts to end the war and legislation aimed at imposing tougher sanctions on Russia.
He said China could play a decisive role in pushing Moscow towards negotiations by using its economic influence over Russia.
Graham also announced that the Trump administration had agreed to move forward with a sanctions package targeting revenue used to finance Russia’s war.
During the visit, he toured a SkyFall production facility that manufactures Ukrainian military drones, including heavy bombers, first-person-view aircraft and interceptor models.
He praised Ukraine’s advances in unmanned warfare and called for closer cooperation between American and Ukrainian defence companies.
The visit placed Graham at the centre of efforts to increase pressure on Moscow during the final days of his life.
Moscow’s enemy
Graham had long ranked among Russia’s most outspoken opponents in Washington.
He supported weapons deliveries to Ukraine, sanctions against Moscow and efforts to hold Russian officials accountable for alleged war crimes.
He also backed measures targeting countries that continued to buy Russian energy.
Russia placed Graham on a wanted list in 2023 after controversy involving edited footage of remarks he made during an earlier meeting with Zelenskyy.
The full recording later showed that two statements condemned by Moscow had been made separately rather than as one continuous remark.
Russia’s state financial-monitoring agency added Graham to its register of “terrorists and extremists” in February 2024, a designation he mocked at the time.
Several Kremlin-aligned commentators reacted to his death with ridicule or celebration, describing him as a warmonger and an enemy of Russia.
Russian lawmaker Alexei Chepa, however, rejected suggestions that Moscow had played any role in Graham’s death.
Foreign-policy hawk
Graham served in the House of Representatives from 1995 to 2003 before representing South Carolina in the Senate from 2003 until his death.
A former Air Force lawyer who rose to the rank of colonel, he became one of Washington’s most prominent advocates of an interventionist foreign policy.
He strongly supported NATO, Ukraine, Israel and Taiwan while repeatedly pushing for tougher military and economic pressure on Iran and Russia.
Graham once ranked among Trump’s fiercest Republican critics but later became a close ally and adviser, particularly on foreign policy, national security and judicial appointments.
Trump described him as a “true American patriot” and ordered US flags lowered in his honour.
Zelenskyy called Graham a defender of freedom, while Israeli Prime Minister Benjamin Netanyahu said Israel had lost one of its greatest friends.
NATO and European leaders also praised his commitment to transatlantic security.
The preliminary medical findings indicate that Graham suffered an aortic dissection linked to cardiovascular disease. But until officials complete the remaining tests and issue a final death certificate, the medical determination will remain provisional.
Claims that Russia, Iran or another foreign government played a role in his death remain unsupported by any publicly verified evidence.
