Chilling question FBI is asking Lindsey Graham's neighbors as 20 agents descend on his home... as senator's final movements spark fears

By PHILLIP NIETO, US POLITICAL REPORTER and CHASE HOPE, POLITICAL REPORTER FOR THE DAILY MAIL Published: 23:44, 13 July 2026 | Updated: 23:59, 13 July 2026 FBI agents grilled Lindsey Graham's neighbors on Monday about what they saw the night he died as speculation swirled after his recent visit to Kyiv and criticism of Iran. One neighbor told the Daily Mail that no less than six agents questioned him about whether he had seen 'anything out of the ordinary' in the hours leading up to Graham's death at age 71 on Saturday night. Around 20 agents descended on Graham's quiet street on Capitol Hill for further investigation after the FBI visited the scene on Sunday. The Daily Mail spotted an unmarked law enforcement car posted outside his residence after the agents left. Graham's spokesperson said the cause of death was aortic dissection due to arteriosclerotic cardiovascular disease, according to preliminary findings by the DC medical examiner's office. But the suddenness of his death has raised suspicions, coming just hours after he toured a drone factory in Ukraine and met with the country's president, Volodymyr Zelensky. Graham was also a fervent supporter of Donald Trump's Iran war and his death has been celebrated by the Islamic regime. Ahead of his trip to Kyiv, Graham was at the NATO summit in Ankara, Turkey, where he met with Syrian President Ahmed al-Sharaa to discuss delivering what he called 'a blow to Iran.' Law enforcement has not found any evidence to suspect foul play and the FBI said it is investigating out of an abundance of caution. But a chorus of hardline Trump loyalists, including Laura Loomer, have speculated there may be something more nefarious.  Half a dozen agents asked one neighbor if he saw 'anything out of the ordinary' in the hours leading up to Graham's death on Saturday night Around 20 agents returned to Graham's quiet street on Capitol Hill as conspiracy theories swirled after he died just hours after returning from a trip to Ukraine Graham had spoken to Trump on Saturday night, hours after landing back from Kyiv, in what Trump said 'could've been his last call.'  The president told NBC's Meet the Press that the senator 'sounded a little bit tired, but perfect.' Trump and Graham discussed the senator's visit to Ukraine where he had been pressing the case against Vladimir Putin. 'Ukraine has exceeded every expectation on the battlefield. Now is the time to apply maximum pressure on Putin to end the bloodbath,' Graham posted on X last week. 'I applaud President Trump's decision to grant Ukraine a license to produce their own Patriot missile interceptors. I believe this will be a giant step forward.' Days before he was in Ukraine, Graham joined a senate delegation at the NATO summit in Turkey.   Democratic Senator Chris Coons said Graham was 'jubilant' on the trip after Trump signaled he would finally move ahead with a Russia sanctions package which had been championed by the South Carolina lawmaker. He met with Syria's Al Sharaa who he said gave the country 'the best chance for a functioning, united Syria.' Graham flew on to Kyiv from Turkey, meeting Zelensky on July 10 and touring the SkyFall drone plant on July 11 before heading home FBI agents can be seen swarming Graham's home for a second time on Monday afternoon An autopsy was performed on Sunday and the Metropolitan Police Department is leading the death investigation 'I very much understand Israel's concerns, but President Al Sharaa has been a true thorn in the side of Iran,' Graham wrote on X on July 8. 'He has dramatically reduced Iran's influence in Syria, which is a giant step forward for the Syrian people and a blow to Iran.' Graham flew from Turkey to Ukraine, where he met Zelensky on July 10 and toured the SkyFall drone plant on July 11 before heading home. 'We have the formula to end this war,' Graham told reporters before flying back to the US. Graham was one of the loudest backers of Trump's war against Iran within the president's inner circle.  For decades, he has been one of the biggest advocates in the GOP for direct confrontation with Tehran. Iranian state television celebrated his death in a broadcast on Sunday morning.  That combination has driven days of unverified speculation online about a foreign hand in his death, none of it supported by investigators. A Lego-themed video from an account supporting the Iranian regime showed a hooded figure entering a mansion at night where Graham is seen collapsing. Prior to his death, pro-Iranian accounts had called for Graham's death, sparking widespread speculation online of foul play The video ends with a shot of a checklist with 'Lindsey' ticked off.  'An Iranian regime account is now claiming Iran assassinated Senator Lindsey Graham,' Trump insider Loomer wrote on X.  Just five days before his death, Graham posted a pro-Iran protester holding a placard showing his head in crosshairs. 'At least they used a good photo of me. Judge me by my enemies,' Graham wrote on X. So far neither Iran nor Russia has been officially linked to Graham's death.   Russia has a documented history of targeting opponents with poisonings, including the 2020 nerve agent attack on opposition leader Alexei Navalny. An autopsy for Graham was performed on Sunday and the Metropolitan Police Department is leading the death investigation. The Office of the Chief Medical Examiner is set to determine the official cause and manner in the coming days.  On Monday, Texas Republican Senator John Cornyn told reporters he wanted to see the results of Graham's toxicology report: 'Given where he was and the sorts of things he was advocating for, I think we just ought to resolve all those questions by seeing what the toxicology reports show.' A person who spoke with Graham the night he died said the senator complained of feeling unwell but refused to seek medical attention.  Graham insisted he would wait until after his scheduled Sunday morning appearance on NBC's Meet the Press, according to Axios.  'I can't die now,' Graham joked. 'I still need to do the Russia sanctions, get Iran sorted out and do Israeli-Saudi normalization.'
