The battle between President Donald Trump and the Federal Reserve has escalated into uncharted territory, as the Justice Department reportedly launched a criminal investigation into Lisa Cook, a member of the Fed’s board of governors whom Trump abruptly fired last month via social media.
The clash, already rattling Washington and Wall Street, has raised alarms about the future of the central bank’s independence — a cornerstone of U.S. economic policy for decades.
A Sudden Firing on Truth Social
On August 25, Trump accused Cook of committing mortgage fraud, alleging she had improperly claimed two different homes — one in Michigan and another in Georgia — as her “primary residence” on mortgage applications in 2021.
In a letter posted to his Truth Social account, Trump declared Cook’s removal “effective immediately,” writing:
“The American people must be able to have full confidence in the honesty of the members entrusted with setting policy and overseeing the Federal Reserve. In light of your deceitful and potentially criminal conduct in a financial matter, they cannot and I do not have such confidence in your integrity.”
Cook, who became the first Black woman appointed to the Fed board in 2022, has flatly denied the accusations. Through her attorneys, she insists she “did not ever commit mortgage fraud.” Her legal team has filed a lawsuit challenging the dismissal, arguing the firing was politically motivated and violated her due process rights.
The Justice Department Steps In
The Wall Street Journal reported Thursday that the Justice Department had opened a criminal probe into the allegations against Cook. Her attorney, high-profile Washington lawyer Abbe Lowell, blasted the move as politically driven.
“The questions over how Governor Cook described her properties from time to time…are not fraud,” Lowell told the Journal. “But it takes nothing for this DOJ to undertake a new politicized investigation, and they appear to have just done it again.”
Lowell has argued that even if Cook had made errors on paperwork before joining the Fed, they would not constitute grounds for removal. “Any such pre-office offense plainly would not have been ‘so infamous in nature as to render the offender unfit to execute any public franchise,’” her legal filing stated.
Trump’s War with the Fed
Trump’s fury at the Federal Reserve is not new. Throughout his presidency, he has openly attacked central bank officials for not delivering the interest-rate cuts he demands, often targeting Fed chair Jerome Powell with insults ranging from “stubborn mule” to “low IQ.”
But his offensive against Cook marks a more direct attempt to reshape the Fed to his liking. Analysts say Trump wants to install governors more willing to slash interest rates, despite inflation concerns.
“This is a kill shot at Fed independence,” Aaron Klein, a senior fellow at the Brookings Institution, told Bloomberg. “Trump is saying the Fed is going to do what he wants it to do, by hook or by crook.”
Hundreds of economists have signed a letter condemning Cook’s firing, calling the allegations against her “unproven” and warning that such actions threaten the “fundamental principle of central bank independence” — a principle they say underpins global trust in the U.S. economy.
Enter Bill Pulte
Trump has not acted alone. One of his fiercest defenders in the episode is Bill Pulte, head of the Federal Housing Finance Agency and a controversial Trump appointee who claims to have pioneered “Twitter philanthropy.”
Pulte first publicized the allegations against Cook on August 20, accusing her of falsifying documents to secure favorable loan terms. He has also lobbed similar accusations at Democratic officials including Rep. Adam Schiff and New York Attorney General Letitia James, both of whom deny any wrongdoing.
During a combative interview on CNBC Thursday, Pulte refused to identify the source of his allegations against Cook, saying only: “I’m not going to explain our sources and methods.” When pressed about whether his actions amounted to political weaponization, Pulte snapped at host Andrew Ross Sorkin: “I don’t need you to help me explain things, Andrew.”
What Comes Next
Cook’s lawsuit challenging her removal is still moving through the courts. The DOJ investigation could drag on for months, leaving uncertainty about her future and fueling fears of broader political interference in the Fed.
The stakes are enormous: the Federal Reserve’s independence has long been a bedrock of U.S. economic stability, shielding monetary policy from day-to-day political battles. If Trump succeeds in ousting Cook and installing loyalists, critics warn it could undermine global confidence in America’s economic management — with ripple effects on markets, borrowing costs, and international trust.
For now, Cook remains defiant. Her lawyers insist she will fight both the allegations and the firing. But in Trump’s Washington, where loyalty often trumps precedent, her battle is shaping up as more than a personal defense — it may be a test of whether the Federal Reserve can remain truly independent under the weight of presidential power.
