Robert Mueller, Former Special Counsel, Dies at 81; Trump Responds with Criticism

Robert Mueller, the former FBI director and special counsel who led the investigation into Russian interference in the 2016 presidential election, has died at the age of 81. His death, reported by MS Now on March 21, 2026, followed a multi-year battle with Parkinson’s disease. Former President Donald Trump responded to the news with a critical statement on his Truth Social platform.

Mueller’s Career and the Russia Investigation

Mueller served as FBI director from September 4, 2001, to September 4, 2013, having been nominated by President George W. Bush. In 2019, he was appointed as special counsel to investigate potential collusion between the Trump campaign and the Russian government during the 2016 election.

The Mueller report concluded that Russia had interfered in the 2016 election to benefit Donald Trump. However, the investigation did not establish sufficient evidence to conclude that members of the Trump campaign conspired or coordinated with the Russian government in these efforts.

Trump’s Reaction and Ongoing Disputes

Following Mueller’s death, Trump posted on Truth Social, stating, “Robert Mueller just died. Good, I’m glad he’s dead. He can no longer hurt innocent people! President DONALD J. TRUMP.”

Trump has consistently characterized the Russia investigation as a “hoax” and has alleged that former President Barack Obama’s administration was responsible for initiating it. These claims were reiterated in his response to Mueller’s death.

In 2025, a spokesperson for former President Obama, Patrick Rodenbush, dismissed Trump’s allegations as “outrageous” and a “weak attempt at distraction,” according to reports from the BBC and the New York Times.

Mueller’s Defense of the Investigation

Prior to his death, Mueller actively defended the integrity of his investigation. In a 2020 op-ed for The Washington Post, he emphasized the importance of the investigation, stating, “Russia’s actions were a threat to America’s democracy. It was critical that they be investigated and understood.”

Mueller also addressed claims that his investigation was illegitimate or motivated by improper motives. He maintained that all decisions made during the investigation, including the case of Roger Stone, were based solely on facts and the law. Stone, a longtime Republican strategist and Trump ally, was convicted in 2019 of seven felony charges related to the Russia probe and later received a presidential pardon.

Parkinson’s Disease Diagnosis and Later Life

Mueller was diagnosed with Parkinson’s disease in the summer of 2021, as reported by the Cleveland Clinic. He retired from the practice of law at the end of that year and concluded his teaching position at his law school alma mater in 2022. His family requested privacy following his death.

Parkinson’s disease is a progressive neurological disorder that affects movement. Symptoms include tremors, slowed movement and balance problems.
