Sen. Lindsey Graham, the prominent Republican from South Carolina who served in the Senate for more than two decades, died after suffering an aortic dissection, his office said Sunday.

Graham died unexpectedly Saturday night, his office announced, shortly after he had returned to Washington after a trip to Ukraine.

In a statement, his spokesperson said a preliminary report from the medical examiner for the District of Columbia found that the 71-year-old senator died of aortic dissection due to arteriosclerotic cardiovascular disease. With aortic dissection, a tear occurs in the wall of the aorta.

According to the Mayo Clinic, aortic dissection is not very common, and its symptoms may be mistakenly attributed to other health conditions. It usually affects men in their 60s and 70s. If the blood from the dissection travels outside the artery, the condition is often fatal.

A former military lawyer who reached the rank of colonel in the Air Force, Graham ran for the Republican nomination for president in 2016. Initially a cutting, vocal critic of then-candidate Donald Trump during the election, Graham became one of the president’s staunchest allies after Trump’s election.

“Senator Lindsey Graham, one of the greatest people and Senators I have ever known, is dead!” Trump posted on his social media platform, Truth, on Sunday. “He was always working, and was a true American Patriot.”

Graham was known as a C student in high school, and was the first member of his family to attend college. His mother died while he attended the University of South Carolina, and his father died of a heart attack during Graham’s first semester of law school.

He served as a judge advocate in the Air Force, eventually becoming the chief prosecutor for the Air Force in Europe.

He was first elected to serve as senator for South Carolina in November 2002.

In a social media post on X, Vice President JD Vance described Graham as one of the most powerful lawmakers, and recalled an incident where he and Graham got into a shouting match over a funding bill for the war in Ukraine.

Later the same day, he wrote in the post, Graham was advocating for rail legislation that Vance supported.

“That was Lindsey Graham,” he wrote. “He fought like hell for the things he believed in, and he was just as willing to go to bat for you when it counted.”

Graham had been scheduled to appear on NBC’s “Meet the Press” on Sunday to discuss his trip to Ukraine. Instead, President Trump appeared in his stead, where he said the senator had been “like a member of the family.”

Trump called into several Sunday news programs to discuss Graham’s death, and said he had spoken to Graham on Saturday evening.

Trump told CNN’s Jake Tapper that the South Carolina senator had said he was “tired.”

The US and Iran have agreed in principle to a deal that would reopen the Strait of Hormuz, in exchange for Tehran’s commitment to dispose of its highly enriched uranium, a US official said, according to a report by The New York Times on Sunday.

The official said that the agreement has not yet been signed and remains subject to final approval by US President Donald Trump and Iran’s Supreme Leader Mojtaba Khamenei, a process that could take several days, noting that the method for disposing of Iran’s highly enriched uranium is still being negotiated.

The proposed deal does not address Iran’s missile stockpile nor include a moratorium on uranium enrichment, the official said, adding that these issues are expected to be handled in future rounds of talks.

According to a Fox News report on Sunday, the official suggested that the US could consider “significant accommodations” on sanctions relief if Iran agrees to make similar concessions regarding its enriched uranium stockpile.

“Our plan is to deal with all of their stockpile of the enriched material,” the official said, adding that Washington sees Tehran making “serious accommodations” not previously seen in earlier negotiations, according to the report.

The official also rejected the idea of any “tolling” mechanism for the Strait of Hormuz, saying such an arrangement would not be acceptable and had not been proposed by either side, the report noted.

According to a separate CBS News report, the official said the administration views the emerging agreement as stronger than the 2015 nuclear deal reached under former US President Barack Obama, which allowed uranium enrichment up to certain levels.

As part of the agreement, the US would lift its blockade on vessels entering and leaving Iranian ports. The official said the US Central Command and Gulf partners would coordinate to ensure safe passage, stressing this should not be viewed as a toll system.

The official also said US Vice President JD Vance, Middle East Envoy Steve Witkoff, and Trump’s son-in-law Jared Kushner have been involved in the talks, adding that Washington is seeking to include all regional allies in the process, the report added.
