Justice Department Opened a Criminal Probe of Fed Chair Jerome Powell, Which a Federal Judge Ruled Was a Pretext to Pressure Him on Interest Rates

Details

On the evening of Sunday, January 11, 2026, Federal Reserve Chair Jerome Powell released a rare written and video statement revealing that the Department of Justice had served the central bank with grand jury subpoenas two days earlier, threatening a criminal indictment tied to his June 2025 congressional testimony about the cost of renovating the Fed's headquarters. Powell did not contest that scrutiny of the project was legitimate, but he called the criminal threat a pretext: "This new threat is not about my testimony last June or about the renovation of the Federal Reserve buildings. It is about whether the Fed will be able to continue to set interest rates based on evidence and economic conditions—or whether instead monetary policy will be directed by political pressure or intimidation."

Two months later, a federal judge agreed with him in unusually blunt terms. The episode would run for four more months — through a quashed subpoena, a failed motion for reconsideration, a dropped investigation, and the confirmation of President Trump's hand-picked successor — and it sits alongside a separate Supreme Court fight over Trump's attempt to fire a sitting Fed governor. Together they amount to the most direct assault on the Federal Reserve's political independence in the institution's history.

What the Renovation Actually Is

The investigation centered on the Fed's multiyear renovation of two of its own historic buildings in Washington: the Marriner S. Eccles Building and the adjacent 1951 Constitution Avenue Building. According to the central bank, neither had been comprehensively renovated since their construction in the 1930s. Powell told senators the Eccles building "was not really safe, and it was not waterproof," and the Fed has posted video of water pouring into the basement in 2017.

The project was first approved by the Fed's board of governors in 2017 — a year before Powell became chair — with an initial estimate of about $1.9 billion. The cost later rose to roughly $2.5 billion. The Fed attributed the increases to design changes made after consultations with review agencies, higher prices for materials, equipment and labor, and unforeseen site conditions including more asbestos than expected and contaminated soil. Critically, the Fed is self-funded and does not draw on taxpayer appropriations for its operations or its buildings.

There is no contract, payment, or business relationship between the Fed's renovation and the president or any private firm connected to him. The administration's line of attack was the opposite of self-dealing: Trump and his allies seized on the Fed's own cost overruns as a cudgel against Powell. Budget chief Russell Vought likened the project to the Palace of Versailles and called Powell "guilty" of "fiscal mismanagement." During a July 2025 hard-hat tour, Trump confronted Powell on camera about the cost, claiming it had reached "about $3.1 billion"; Powell told the president, on live television, that he was wrong.

The Pressure Campaign Behind the Probe

The renovation fight did not arise in a vacuum. It followed months of public attacks by Trump demanding that the Fed cut interest rates far faster than its policymakers were willing to. The Fed had cut rates at each of its final three meetings of 2025 but signaled it would hold steady amid inflation worries — too slow for the president, who at Davos in January 2026 reiterated that the U.S. should pay "the lowest interest rate of any country in the world."

In a December 2025 social media post, Trump said he wanted a Fed chair who would cut rates when the stock market rose — the reverse of conventional monetary policy — and warned, "Anyone that disagrees with me will never be the Fed chairman!" He repeatedly insulted Powell, calling him "TOO ANGRY, TOO STUPID, & TOO POLITICAL" and "a TOTAL LOSER," and threatened to fire him outright. Those statements would later become central evidence in court.

A Federal Judge Calls It a Pretext

In February 2026, the Fed's board challenged the subpoenas in court through proceedings that were initially sealed. On March 11, Chief Judge James Boasberg of the U.S. District Court for the District of Columbia quashed the two subpoenas, and his opinion — unsealed two days later — was scathing.

Boasberg wrote that "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," while "the Government has produced essentially zero evidence to suspect Chair Powell of a crime; indeed, its justifications are so thin and unsubstantiated that the Court can only conclude that they are pretextual." He found "abundant evidence that the subpoenas' dominant (if not sole) purpose is to harass and pressure Powell either to yield to the President or to resign and make way for a Fed Chair who will."

The judge took direct aim at the theory that cost overruns alone suggested fraud: "buildings often go over budget. That fact, standing alone, hardly suggests that a crime occurred." He noted that the Fed's independent inspector general had audited the renovation years earlier and raised no concerns about fraud. As for Powell's testimony, Boasberg wrote that the only basis he could find to suspect Powell of lying to Congress "is that he testified at a hearing. The Government might as well investigate him for mail fraud because someone once saw him send a letter." Quoting Trump's own posts at length, the judge summarized: "the President spent years essentially asking if no one will rid him of this troublesome Fed Chair."

Commentators across the spectrum noted that the ruling's significance lay in its refusal to separate presidential rhetoric from prosecutorial action. As an MSNBC opinion piece put it, Boasberg "took President Donald Trump at his word" and treated motive as "the case," not a side issue. Notably, the criticism was bipartisan: even Republican senators who faulted the project's cost said there was no evidence of a crime. Sen. Thom Tillis (R-N.C.) called the probe a "vindictive prosecution", and Sens. Kevin Cramer, Mike Crapo, and John Kennedy expressed similar skepticism.

The Investigation Collapses

U.S. Attorney for the District of Columbia Jeanine Pirro, a longtime Trump ally, fought the ruling. At a combative press conference she labeled Boasberg an "activist judge" who had "neutered" the grand jury, and her office filed a motion for reconsideration. On April 3, Boasberg refused to reconsider, saying the government "did not come close" to meeting the bar. In its filings, the Justice Department effectively conceded it lacked proof of a crime, arguing instead that the renovation's cost gave it "1.2 billion reasons" to investigate.

On Friday, April 24, Pirro abruptly dropped the probe, saying her office would instead defer to the Fed's inspector general — who had, in fact, been reviewing the renovation's cost overruns since July 2025 at Powell's own request. Pirro warned she "will not hesitate to restart a criminal investigation should the facts warrant," leaving the door open. The reversal came days after two prosecutors from her office made an unannounced attempt to tour the construction site and were denied entry, and two days after Trump publicly mused that Powell might be "taking money on construction" — "I can't imagine that 'Too Late' is taking money on construction. I can't. But it's possible. But we have to find out."

Why It Was Dropped: Clearing the Path for Warsh

The timing was not coincidental. Sen. Tillis, a Banking Committee member who was not seeking reelection and had broken with Trump before, had vowed to block confirmation of Trump's Fed chair nominee, Kevin Warsh, unless the Powell investigation ended. With 13 Republicans and 11 Democrats on the committee, a single GOP defection would have deadlocked the nomination. As long as the probe continued, Warsh's path was blocked.

Two days after Pirro folded, Tillis announced he had received Justice Department assurances that "the only way an investigation would be opened would be a criminal referral" from the inspector general, and that any appeal of Boasberg's ruling would concern "legal principles and not for the purpose of reissuing subpoenas." He dropped his hold. On April 29, the Banking Committee advanced Warsh on a 13–11 party-line vote — what Sen. Elizabeth Warren said was the first fully partisan committee vote on a Fed chair nominee in the panel's history. The full Senate confirmed Warsh 54–45 on May 13, with every Republican and Democrat John Fetterman in favor; he took over as chair when Powell's term expired on May 15.

Warren called Warsh a "sock puppet" for Trump and warned the confirmation would erode Fed independence. Warsh, a Fed governor from 2006 to 2011 and a fellow at the conservative Hoover Institution, pushed back at his April 21 hearing, testifying that "monetary policy independence is essential" and that he had never promised the White House he would cut rates: "I will be an independent actor if confirmed as chair." He also defended the right of presidents to voice views on rates, saying such comments do not infringe on independence.

Powell Stays On

In an extraordinary move, Powell announced he would not leave the Fed entirely after his chairmanship ended. At his final press conference as chair on April 29, Powell confirmed he would remain on the Board of Governors — a position whose term runs to 2028 — making him the first outgoing chair to stay on the board since Marriner Eccles in 1948. He tied the decision directly to the legal attacks: "I had long planned to be retiring. The things that have happened really in the last three months have, I think, left me no choice but to stay until I see them through." He added that he would "not leave the board until this investigation is well and truly over with transparency and finality," noting pointedly that Pirro had said she would not hesitate to restart it. As a governor, Powell said, he would "keep a low profile," because "there's only ever one chair of the Federal Reserve Board."

The Parallel Front: The Attempt to Fire Lisa Cook

The Powell probe was not the administration's only move against the central bank. In August 2025, Trump attempted to fire Fed Governor Lisa Cook — the first time in the Fed's 112-year history a president has tried to remove a governor — citing unproven allegations of mortgage fraud on paperwork predating her time at the Fed. The allegations were surfaced by Federal Housing Finance Agency director Bill Pulte, who also raised similar claims against other Trump opponents and declined to say whether the tip came from inside the government.

Lower courts blocked the removal, and on January 21, 2026 — ten days after Powell revealed his subpoena — the Supreme Court heard arguments in Trump v. Cook. Across nearly two hours, all nine justices expressed doubts about the president's claim of unreviewable power to fire Fed governors. Justice Brett Kavanaugh, a Trump appointee, said the administration's position "would weaken, if not shatter, the independence of the Federal Reserve." On June 29, 2026, the Court ruled 5–4 that Cook must remain on the board while her challenge proceeds, holding that Trump had failed to give her the procedural protections the law requires and pointedly noting the "tradition of central banking protected from political interference" — even as a companion ruling expanded the president's power to fire officials at other independent agencies. Powell, who attended the arguments in person, called the case "perhaps the most important legal case in the Fed's 113-year history."

What the Evidence Says About Fed Independence

The stakes of the episode turn on a contested but well-studied question: does insulating a central bank from politics actually matter? The bulk of the economic literature says yes, with caveats.

The foundational work — Cukierman, Webb, and Neyapti (1992) and successors — found that greater central-bank independence correlates with lower inflation in developed economies, and that high turnover of central-bank governors correlates with higher inflation in developing ones. A 2021 study by Carola Binder found that increased political pressure on central banks is associated with higher and more persistent inflation.

The most directly relevant recent work is an IMF working paper (March 2026) that built a cross-country dataset of politically motivated governor transitions. Its finding maps almost exactly onto the current situation: political pressure does deliver lower rates and a short-run boost to growth, but "over time, inflation rises and central bank credibility declines," with the damage "especially" severe when the incoming governor favors unorthodox policy. Long-term inflation expectations, the authors found, rise only when a politically appointed governor holds unorthodox views — a reminder that the identity and orthodoxy of a successor like Warsh matters as much as the act of interference itself.

The consensus is not unanimous. Campillo and Miron (1997) found that independence had no measurable effect on inflation once controls for openness, debt, and political stability were included, and other researchers argue that broader rule-of-law institutions, not central-bank independence per se, explain the correlation. The American Institute for Economic Research notes that independence is no guarantee of good behavior in either direction — citing evidence that the Fed itself may have delayed tightening under the Biden administration as Powell sought reappointment. A recurring theme across the literature, underscored by the CEPR, is that "de facto independence matters: strong legal protections are no guarantee against political interference" — which is precisely why a pressure campaign that never results in a firing or a statutory change can still do damage.

Market Reaction

Financial markets treated Fed independence as a real and priceable risk, though the signal is muddied by the simultaneous war in Iran and its energy shock. Through 2025 and into early 2026, gold roughly doubled and topped $5,000 for the first time, with analysts citing a less-independent Fed among the drivers of safe-haven demand. When Warsh — known historically as an inflation hawk and a critic of the Fed's bond-buying — was nominated in late January, gold plunged 11.4% in a single session as some investors read the pick as a signal the Fed would remain independent and willing to keep rates high. As one Macquarie strategist cautioned, however, "Warsh is not the Fed's guy, he is Trump's guy."

By his confirmation hearing, markets had largely calmed: analysts described Warsh's testimony as "broadly dovish, pragmatic, and respectful of institutional independence," and Treasury yields and equities were relatively stable. The takeaway is not that markets shrugged off the threat, but that they responded most to signals about whether the Fed's independence — and its inflation-fighting credibility — would survive intact.

Assessment

Judged purely on outcomes, the institution held. An independent judiciary quashed the subpoenas in withering terms, the criminal case collapsed without an indictment, Republican senators publicly rejected its merits, Powell refused to resign and stayed on to defend the board, the Supreme Court ruled 5–4 in June 2026 that the president could not fire Governor Cook without due process, and the incoming chair pledged independence. That is why this entry is rated Concerning rather than Big Deal.

But the action being rated is the conduct, not only its result. Deploying the Justice Department's criminal power against the chair of the central bank to influence interest-rate policy is a serious ethical breach, and a federal judge found in plain language that this is what happened. The precedent — that a president can manufacture a criminal pretext to pressure or oust a Fed official — does not disappear because this particular attempt failed; the inspector-general "off-ramp" leaves the threat formally alive, the Cook case—though she prevailed on due-process grounds at the Supreme Court in June 2026—remains unresolved on the underlying "for cause" question, and a hand-picked successor now leads the institution. The empirical record is consistent that this kind of de facto interference, even when it stops short of a firing or a legal change, raises long-run inflation risk and erodes the credibility that makes a central bank effective. The harm here is to a norm that took decades to build and can be damaged without ever being formally repealed.
