Mueller Probe Accused of Bias and Rule Violations in Trump Pursuit

A whistleblower FBI agent has alleged that Robert Mueller's special counsel investigation into Donald Trump's 2016 campaign was marred by political bias, misconduct, and procedural violations aimed at targeting the then-president.

The claims, detailed in a December 2020 internal FBI probe and recently highlighted in documents obtained by Senate Judiciary Committee Chairman Chuck Grassley (R-IA), describe a "Let's get him" atmosphere, including anti-Trump cartoons on office walls and alcohol consumption during work hours. The agent, assigned to Mueller's team, reported "overzealous thoughts" and bias permeating the probe.

Specific violations include:

• Lack of authority to investigate Trump associate Tom Barrack as an unregistered UAE agent; the FBI's Washington Field Office declined, but Mueller's team proceeded, leading to Barrack's 2022 acquittal.
• Abuse of FISA warrants, including FBI lawyer Kevin Clinesmith altering an email for a warrant on Carter Page, resulting in his guilty plea and probation.
• Security breaches by prosecutor Zainab Ahmad, who carried classified notebooks without proper safeguards.
• Pressure on FBI agent Michelle Taylor to alter derogatory remarks about Trump by former FBI Deputy Director Andrew McCabe; Taylor refused and later left the FBI.

Grassley sent a letter to Attorney General Pam Bondi and FBI Director Kash Patel demanding all related emails, files, and records by March 29, 2026. The Mueller probe, costing over $30 million from 2017-2019, found no evidence of Trump-Russia collusion. John Durham's 2023 report labeled it "seriously flawed."
