Whistleblower: Mueller Probe Violated Rules to Target Trump

An FBI agent who worked on Robert Mueller’s team has accused the investigation of widespread bias and improper behavior. The agent said anti-Trump cartoons and drinking on the job contributed to a “let’s get him” atmosphere.

Internal probe and whistleblower claims

The agent was interviewed in December 2020 during an internal FBI review tied to supervisory analyst Brian Auten. The whistleblower claims the Mueller probe violated rules and aimed to target Trump.

Senate Judiciary Committee Chairman Chuck Grassley (R-Iowa) sent a letter to Attorney General Pam Bondi and FBI Director Kash Patel. He said the account confirms long-standing concerns about political bias.

Allegations of improper prosecutions

Grassley’s letter described a case brought against Tom Barrack, a longtime Trump associate. The FBI Washington Field Office had declined to open an inquiry, but the Mueller team proceeded to arrest and charge Barrack.

After a costly legal fight, a jury acquitted Barrack in 2022. The letter also states he now serves as US ambassador to Turkey.

FISA surveillance concerns

The agent accused the special counsel team of chronic misuse of FISA warrants against campaign advisers. The staff reportedly renewed warrants even when FBI field agents objected.

According to the account, an investigator flagged errors before a fourth renewal. FBI lawyer Kevin Clinesmith told him, “We can’t send this.” Clinesmith later pleaded guilty to altering an email tied to a Carter Page FISA application.

Other misconduct allegations

The letter names Mueller prosecutor Zainad Ahmad for violations of security rules. It says she brought classified material to a field office without authorized safeguards and stored it at home.

Former deputy director Andrew McCabe allegedly used derogatory language about President Trump in interview notes. DOJ prosecutors then pressured agent Michelle Taylor to change the document’s tone, the account says. Taylor refused and later left the FBI.

Office culture and key personnel

The agent described a general atmosphere of bias led by prosecutor Aaron Zelinsky. The letter claims the office displayed anti-Trump caricatures and cartoons.

Zelinsky handled prosecutions of Roger Stone, George Papadopoulos and Michael Caputo. He resigned from the Department of Justice in January 2025.

Timeline, costs and follow-up investigations

Mueller’s probe concluded in March 2019 after about two years and more than $30 million in spending. The special counsel found no evidence of collusion between the Trump campaign and Russia.

In May 2023, special counsel John Durham released a report calling the Russia investigation “seriously flawed.” Durham said the FBI at times discounted material information that did not fit its collusion narrative.

Next steps

Grassley has asked Bondi and Patel to produce emails, files and personnel records tied to the agent’s allegations by March 29. The senator said the American public deserves answers.
