Sources indicate that in the hours before his death, Graham had spoken with President Donald Trump and had brushed off suggestions to seek medical attention. During conversations about ongoing international conflicts and legislative matters, Graham reportedly felt unwell but stated he would see a doctor on Sunday morning after a scheduled appearance on NBC's Meet the Press.

Graham, a prominent Republican from South Carolina, was a vocal supporter of U.S. involvement in global conflicts, including the Russia-Ukraine war and tensions with Iran. He had recently traveled to Ukraine and met with President Volodymyr Zelensky.

FBI agents were present at Graham's residence, prompting some speculation. However, FBI Director Kash Patel stated his agency was providing all necessary resources.

Political commentators and figures offered tributes and shared their reactions. Former President Trump remembered Graham as a "true American Patriot." Vice President JD Vance recalled Graham as someone who "fought like hell for the things he believed in." Congressman Jim Clyburn, a Democrat from South Carolina, noted that their "political relationship was sometimes partisan and passionate, but always pleasant and productive on behalf of the people of South Carolina."
