The New York Times has reported that Robert Mueller, the former FBI director and special advisor, has been diagnosed with Parkinson’s disease. As a result, the House Oversight and Government Reform Committee is looking to withdraw a subpoena that was previously issued.

Back in the 2000s, Mueller was called to testify regarding the FBI’s response to investigations into the controversial financial advisor Jeffrey Epstein. The current House Oversight Committee is examining how the George W. Bush administration managed the lawsuit related to Epstein, who had already entered a plea agreement.

According to a tweet from Eric Dorgerty, Mueller cannot testify before Congress due to his health condition: “Robert Mueller is currently suffering from Parkinson’s disease, so according to his family, he cannot testify before Congress.”

Mueller, who resides in a memory care facility, has not disclosed specific details about his condition. Reports indicate that the House Oversight Committee retracted the subpoena issued on August 18 because of his health issues.

During Trump’s first term, the Department of Justice appointed Mueller as a special advisor to investigate possible Russian interference in the 2016 presidential election. His report ultimately determined that there was no collusion between Russia and Trump’s campaign.

Jeffrey Epstein, who pleaded guilty to sexual charges in 2008, reportedly died by suicide in a Manhattan prison while awaiting trial on new allegations in 2019. He maintained a network of connections with a variety of celebrities, politicians, and executives, even as a convicted sex offender. Among his known associates were L Brands founder Lex Wexner, director Woody Allen, and Prince Andrew.

Microsoft co-founder Bill Gates also met with Epstein several times, sometimes alongside employees from the Bill and Melinda Gates Foundation. Despite concerns from Gates’ then-wife Melinda, he had interactions with the registered sex offender as recently as late 2019.
