A Criminal Case Built on Nothing: Inside the DOJ's Evidence-Free Investigation of Fed Chair Jerome Powell

On March 3, 2026, inside a sealed courtroom in Washington, D.C., a federal prosecutor was asked a straightforward question by Chief Judge James E. Boasberg: What evidence is there of fraud or criminal misconduct by Federal Reserve Chair Jerome Powell?

"We do not know at this time," replied George A. Massucco-LaTaif, chief of the criminal division for U.S. Attorney Jeanine Pirro's Washington office [1].

When pressed on what false statements Powell allegedly made before Congress, Massucco-LaTaif offered the same answer: "Well, we don't know is my first answer" [2].

That exchange, revealed in a transcript unsealed on March 24, has laid bare what critics call the most brazen use of prosecutorial power against a sitting central bank chief in the Federal Reserve's 113-year history — a criminal investigation launched without evidence of a crime.

The Pretext: A $2.5 Billion Renovation

The ostensible basis for the investigation is mundane: a multi-year renovation of the Federal Reserve's Marriner S. Eccles Building and its adjacent East Building in downtown Washington. The project, which began planning in 2017 and broke ground in 2022, aims to bring the aging structures into compliance with modern safety and accessibility codes [3].

Original cost estimates placed the project at $1.9 billion in 2021. By 2025, that figure had risen to $2.5 billion — roughly $600 million over initial projections [4]. The Fed has attributed the overruns to discoveries of lead paint and asbestos during demolition, a higher-than-expected water table complicating excavation, and inflation in construction materials [3].

Cost overruns of this magnitude are common in major federal construction. The Fed's own legal team cited the St. Elizabeth's campus renovation, which ran $1.5 billion over budget, and the Capitol Visitor Center, whose costs doubled from initial estimates [1]. No criminal charges resulted from either project.

During his semiannual testimony before the Senate Banking Committee on June 25, 2025, Powell was questioned about the renovation's rising costs [5]. His answers to those questions became the narrow basis upon which the entire criminal probe would be constructed.

The Investigation Takes Shape

In November 2025, U.S. Attorney Jeanine Pirro — a Trump appointee and former Fox News host — opened a criminal investigation through her Washington, D.C., office into whether Powell made false or misleading statements to Congress about the scope and cost of the renovation [6]. On January 9, 2026, federal prosecutors served grand jury subpoenas on Powell and the Federal Reserve's Board of Governors, marking the first time in the institution's history that sitting leadership faced potential prosecution from a presidential administration [7].

Powell responded publicly on January 11, releasing a statement through the Federal Reserve's website. He did not merely deny wrongdoing — he named the motive directly: "The threat of criminal charges is a consequence of the Federal Reserve setting interest rates based on our best assessment of what will serve the public, rather than following the preferences of the President" [8].

The timing supports Powell's claim. Throughout 2025, President Trump publicly attacked Powell for not lowering interest rates faster. The federal funds rate had been reduced from 5.33% in September 2024 to 4.33% by April 2025, and further to 3.64% by early 2026, but Trump demanded more aggressive cuts [9]. The investigation opened just weeks after the Fed held rates steady at its November meeting.

"Essentially Zero Evidence"

The sealed March 3 hearing before Judge Boasberg was supposed to be the government's opportunity to justify its subpoenas. Instead, it became a forensic exposure of a case with no foundation.

Beyond the prosecutor's admissions about lacking evidence of fraud or false statements, the transcript reveals that Massucco-LaTaif's primary justification was financial rather than legal: "There are 1.2 billion reasons for us to look into it," he said, referencing the dollar figure of cost overruns [2]. A cost overrun, however large, is not a crime absent evidence of fraud, embezzlement, or intentional misrepresentation.

Eight days later, on March 11, Judge Boasberg issued his ruling quashing both subpoenas. The opinion, unsealed on March 13, is among the most pointed judicial rebukes of prosecutorial conduct in recent memory [10]:

"A mountain of evidence suggests that the Government served these subpoenas on the Board to pressure its Chair into voting for lower interest rates or resigning."

"The Government has offered no evidence whatsoever that Powell committed any crime other than displeasing the President."

"The Court is thus left with no credible reason to think that the Government is investigating suspicious facts as opposed to targeting a disfavored official."

Boasberg further noted that most members of the Senate Banking Committee, including majorities from both parties, stated they did not believe Powell committed any crime during his testimony [1].

Political Context and the Warsh Nomination

The investigation did not exist in a vacuum. On January 30, 2026 — three weeks after the subpoenas were served — Trump nominated former Federal Reserve Governor Kevin Warsh to succeed Powell as Fed chair [11]. Critics argued the investigation was designed to pressure Powell into resigning early, clearing the way for a chair more amenable to aggressive rate cuts.

Powell responded to the nomination by stating he would not leave the Board of Governors until the investigation concluded with "transparency and finality," and that he would continue serving in an acting capacity until Warsh was confirmed [12]. That confirmation now faces its own obstacles: Senator Thom Tillis (R-N.C.) has pledged to block Warsh's confirmation until the Powell investigation is fully closed, calling the probe "frivolous" [13].

The investigation also intersected with Trump's broader campaign against Fed independence. The administration had separately attempted to fire Fed Governor Lisa Cook, a case that reached the Supreme Court [14]. Together, these actions represented an unprecedented multi-front assault on the central bank's operational autonomy.

Market Reaction and Economic Uncertainty

Financial markets responded to the investigation with immediate, if temporary, turbulence. When Powell confirmed the probe on January 11, stock futures fell sharply — Nasdaq 100 futures dropped approximately 0.8%, S&P 500 futures fell roughly 0.5%, and Dow Jones Industrial Average futures declined about 0.4% [15].

The bond market impact was more nuanced. The 10-year Treasury yield, a benchmark for borrowing costs across the economy, showed increased volatility during the investigation period. Yields rose in January 2026 as investors questioned whether the Fed's independence could withstand political pressure, then fell as markets assessed the investigation's lack of substance, before climbing again by late March [16].

Deutsche Bank warned that a loss of central bank independence could lead to "currency and bond market collapse," citing heightened risks of inflation and financial instability [15]. TD Cowen's Washington Research Group expressed concern that the investigation "will lead to higher interest rates as the market questions the Fed's ability to respond if there are signs of inflation" [15].

By March 2026, bond traders had priced out any chance of a Fed rate cut for the remainder of the year, a shift driven by both the political uncertainty and the Fed's own hawkish signaling on persistent inflation [17].

The Question of Prosecutorial Accountability

Pirro's response to Judge Boasberg's ruling was defiant. She called him an "activist judge" and declared that "Jerome Powell today is now bathed in immunity," vowing to appeal [13]. The Department of Justice formally announced it would challenge the ruling, extending what has become an unprecedented institutional confrontation between the executive branch and the central bank [18].

The question of what accountability Pirro and her office face for pursuing a case the judge found to be pretextual is, by most legal scholars' assessment, largely theoretical. The Department of Justice's internal oversight structure — split between the Office of Professional Responsibility and the Office of the Inspector General — has been criticized by organizations including the Brennan Center for Justice as a "broken accountability system" [19]. The National Association of Criminal Defense Lawyers has documented how "the vast majority of known instances of prosecutorial misconduct come to light only during the course of a drawn-out trial or appellate proceeding" [20].

Federal prosecutors enjoy broad discretionary authority under the Principles of Federal Prosecution in the Justice Manual, and courts have historically been reluctant to second-guess charging decisions [21]. Boasberg's ruling is notable precisely because it breaks from that tradition — a sitting federal judge concluded, based on the evidence presented, that the prosecution's stated rationale was "pretextual."

The Renovation in Broader Perspective

Lost in the political theater is the actual question of whether the Fed's renovation spending warrants scrutiny — through appropriate oversight channels. The $600 million in cost overruns, while common in federal construction, represent real taxpayer-adjacent costs. The Fed is self-funded through its operations and does not receive congressional appropriations, but its expenditures reduce the surplus it remits to the U.S. Treasury [3].

Congressional oversight committees have the authority and institutional competence to investigate cost overruns through hearings, audits, and Government Accountability Office reviews. Several members of the Senate Banking Committee questioned Powell about the costs during his June 2025 testimony — the normal functioning of legislative oversight [5].

What the DOJ investigation did was convert a legitimate oversight question into a criminal matter without evidence of criminal conduct, creating what Judge Boasberg characterized as a mechanism for political coercion.

Historical Precedent and Fed Independence

The tensions between presidents and Fed chairs have a long history, but none have previously escalated to criminal prosecution. President Richard Nixon pressured Fed Chair Arthur Burns to ease monetary policy ahead of the 1972 election — pressure Burns reportedly yielded to, contributing to the inflation of the 1970s [22]. President Harry Truman clashed with Fed leadership over bond rate pegs in what became the Treasury-Fed Accord of 1951 [22].

In neither case did the executive branch deploy the criminal justice system against a sitting Fed chair. Research from the University of Maryland has documented how political pressure on the Fed "strongly and persistently raises inflation and inflation expectations but has little impact on economic activity" — a finding that underscores why central bank independence is considered a macroeconomic safeguard [23].

The Powell investigation sets a precedent that future administrations could exploit: the use of criminal probes, even those built on no evidence, as instruments of monetary policy pressure. Whether the appellate courts sustain or reverse Boasberg's ruling will determine whether that precedent hardens into institutional reality.

What Comes Next

The DOJ's appeal is expected to be heard by the U.S. Court of Appeals for the D.C. Circuit in the coming months. Powell has stated he will remain on the Board of Governors through the process [12]. Warsh's confirmation remains stalled, with Senator Tillis's hold creating bipartisan uncertainty about the Fed's leadership transition [13].

The unsealed transcript of the March 3 hearing has given the public a rare, unfiltered look at the evidentiary basis — or absence thereof — behind a criminal investigation of the nation's most powerful economic official. What that transcript reveals is a prosecution that, in the judge's assessment, was never about building renovation costs. It was about interest rates, political leverage, and the question of whether the Federal Reserve answers to the law or to the president.
