Sen. Lindsey Graham, R-S.C., has repeatedly called for the assassination of Russian President Vladimir Putin.

Now, after Graham's sudden death, some are wondering if Putin got his wish first.

In March of 2022 Graham posted on X: "Is there a Brutus in Russia? Is there a more successful Colonel Stauffenberg in the Russian military? The only way this ends is for somebody in Russia to take this guy out. You would be doing your country - and the world - a great service."

Asked about the matter later at a press conference, Graham urged the people of Russia to "rise up and end this reign of terror."

"I hope he will be taken out, one way or the other. I don't care how they take him out. I don't care if we send him to The Hague and try him. I just want him to go," said Graham during a press conference shortly after Russia invaded Ukraine.

Among those raising the possibility of Putin's involvement in Graham's death is Russian opposition sociologist Igor Eidman, who argued that the Kremlin may have had both a motive and an opportunity to target the South Carolina Republican.

His comments, however, remain speculative.

Eidman pointed to Graham's prominent role as one of Congress' strongest advocates for Ukraine and one of Russia's harshest critics.

According to Eidman, the senator's continued push for increased military assistance to Kyiv and tougher sanctions against Moscow may have made him a target in the eyes of the Kremlin.

The opposition commentator also noted Graham's recent visit to Ukraine, suggesting—without presenting evidence — that a hypothetical poisoning using a slow-acting substance could have occurred during the trip.

Eidman speculated that Russian intelligence services might have been capable of conducting such an operation through clandestine networks operating inside Ukraine.

He acknowledged that his theory was based on circumstantial considerations rather than direct proof.

No law enforcement agency, intelligence service, or government has publicly concluded that Russia played any role in Graham's reported death. No forensic evidence, intercepted communications, witness testimony, or official intelligence assessments have been released supporting Eidman's claims.

The allegations nevertheless draw attention to Graham's yearslong confrontation with the Kremlin.

Throughout Russia's war against Ukraine, Graham emerged as one of the most vocal proponents of expanded U.S. military assistance to Kyiv.

He repeatedly called for stronger sanctions on Russia and advocated providing increasingly sophisticated weapons systems to Ukraine.

According to Eidman, Graham had recently stated that President Donald Trump supported legislation imposing what Graham described as "hellish sanctions" against Russia.

Eidman argued that Russian officials may have viewed Graham as one of the key figures influencing Trump's evolving approach toward Moscow.

Those assertions also remain speculative.

For years, Graham has been a frequent target of criticism from senior Russian officials and state media.

Russian Foreign Ministry spokeswoman Maria Zakharova has repeatedly denounced Graham's remarks as provocative and irresponsible.

Former Russian President Dmitry Medvedev, now deputy chairman of Russia's Security Council, has also regularly attacked Graham on social media, accusing him of promoting escalation of the conflict.

Russian state television commentators have often portrayed Graham as one of Moscow's principal political adversaries in Washington, criticizing his support for Ukraine and his calls for additional military assistance.

Following some of Graham's previous remarks regarding Putin, Russian officials discussed possible legal action against the senator under Russian law and publicly condemned statements they characterized as encouraging violence or regime change.

Those exchanges contributed to Graham's reputation inside Russia as one of the Kremlin's most outspoken American critics.

Still, political hostility does not establish responsibility for his death.

Security analysts have long noted that Russia has been accused by Western governments of involvement in several poisonings and assassination attempts targeting Kremlin critics and defectors over the past two decades.

Moscow has consistently denied those allegations.
