Peter Strzok texted "We'll stop him" about Donald Trump while running the Russia investigation.
That was just the beginning.
Now a second FBI agent has stepped forward – and what he saw inside Mueller's operation makes Strzok look like a footnote.
The "Let's Get Him" War Room
This wasn't a sober investigation searching for truth.
Anti-Trump cartoons plastered the office walls.
Agents drank alcohol on the job.
And according to the whistleblower – an FBI agent assigned directly to Mueller's team – a single attitude drove every decision: "Let's get him."
The agent's account, first made during a December 2020 internal FBI interview, was kept buried until Senate Judiciary Committee Chairman Chuck Grassley sent a letter to Attorney General Pam Bondi and FBI Director Kash Patel this week.
Grassley didn't mince words.
The allegations confirm "long-standing concerns that political bias rotted the decision-making process within the Mueller team," he wrote.
Rotted.
That's the word a sitting chairman of the Senate Judiciary Committee used to describe an investigation that burned through over $30 million in taxpayer money and consumed Trump's entire first term.
McCabe's Contempt and the Agent Who Refused to Lie
The misconduct didn't stop at hostile office décor.
Former FBI Deputy Director Andrew McCabe spoke about Trump in openly derogatory terms during an official, on-the-record interview.
Justice Department prosecutors then pressured a female FBI agent to scrub the document – to rewrite the language so McCabe's contempt for the sitting president wouldn't show in the official record.
She refused.
She left the agency shortly after.
That's not a lapse in judgment.
That's a deliberate attempt to doctor evidence of political bias from the file of an investigation already under scrutiny for political bias.
FBI lawyer Kevin Clinesmith ran the same playbook.
Assigned to Mueller's team, Clinesmith later pleaded guilty to altering a CIA email tied to a FISA surveillance warrant targeting Trump campaign adviser Carter Page – changing the document to make it appear the CIA had said Page was not a government source, when the agency had actually described him as an operational contact.
His punishment: 12 months of probation.
His law license was briefly suspended, then reinstated.
Warrants Renewed When the Evidence Said Stop
The whistleblower's most explosive charges involve systematic abuse of FISA surveillance warrants.
Mueller's team renewed warrants monitoring Trump campaign advisers even after the surveillance had produced zero evidence of wrongdoing – and even after investigators had confirmed the targets were cooperating fully.
In one case, the whistleblower warned colleagues directly: the target was being honest with investigators and the warrants were producing nothing.
The response from Clinesmith when the agent tried to document necessary corrections to a warrant application: "We can't send this."
The warrants kept getting renewed anyway.
The same pattern played out with Trump ally Tom Barrack, chairman of the 2017 inaugural committee.
Mueller's team opened a case against Barrack even after the FBI's Washington Field Office had already declined to pursue him.
They arrested Barrack, threw him in jail, and charged him with acting as a foreign agent of the United Arab Emirates.
A jury acquitted him in 2022.
Barrack now serves as U.S. ambassador to Turkey.
Prosecutor Zainab Ahmad – a protégé of Obama Attorney General Loretta Lynch – repeatedly violated security protocols by transporting classified materials without proper security procedures, including carrying a classified notebook from her home to official FBI meetings.
Bondi and Patel Have Until March 29
This isn't the first confirmation that Mueller's operation was rotten from the inside.
Special Counsel John Durham spent four years documenting how the FBI launched its Trump-Russia probe on uncorroborated intelligence and then ignored every piece of evidence that ran counter to the collusion narrative.
Durham called it "seriously flawed."
What this whistleblower adds is something Durham never had: a firsthand account from inside the room.
He watched McCabe's contempt get scrubbed from the official record.
He watched FISA warrants get renewed after the evidence had already cleared the targets.
He watched Clinesmith kill his documented objections.
Grassley has given Bondi and Patel a hard deadline – produce all emails, internal files, and personnel records related to these allegations by March 29.
For the first time since Mueller's witch hunt began, the people being asked to hand over the records are not the same people who buried them.
Bondi and Patel know where the files are.
Now the only question is whether anyone on Mueller's team finally answers for what they did.
