The Supreme Court blocked President Trump from immediately firing Federal Reserve Gov. Lisa Cook on Monday. In a 5-4 decision, the justices ruled that Cook should be allowed to remain in her role as a key decision maker at the nation’s most important financial institution while she challenges her dismissal in court.
“Only after Cook has had the opportunity to respond to the charges made against her may a final decision be made,” Chief Justice John Roberts wrote in the majority opinion.
Roberts added that allowing Trump to fire Cook without a proper legal process would prove “corrosive of the independence” of the Federal Reserve.
The decision in Cook’s favor comes in stark contrast to a separate ruling from the court on Monday in which the justices granted the president more power to fire government officials. In the case of Rebecca Slaughter, a high-ranking member of the Federal Trade Commission, the justices not only found that Trump had the authority to dismiss her, but also overturned a 91-year-old legal precedent that had protected leaders of many independent federal agencies from being fired without cause.
Monday’s ruling doesn’t mean that Cook is safe from being fired — only that she can stay in her role while courts consider her lawsuit arguing that Trump fired her without proper cause.
The clash between Trump and Cook started in August when Trump took to social media to announce, in an unprecedented move, that he was firing her after one of his allies accused her of mortgage fraud.
“You are hereby removed from your position on the Board of Governors of the Federal Reserve, effective immediately,” Trump wrote in a letter posted to his Truth Social network, adding that the allegation “calls into question your competence and trustworthiness as a financial regulator.”
Cook sued Trump in response, calling the president’s actions “unprecedented and illegal” and setting up a landmark legal fight over the Fed’s independence. That case is still ongoing.
“This was never about mortgage documents signed years before I became a Federal Reserve governor. It was an attempt to remove me on a manufactured pretext because I refused to bow to political pressure,” Cook wrote in a statement following Monday’s decision.
Trump responded to the ruling as well, writing in a Truth Social post that his administration “will take appropriate action immediately to make sure that someone who has committed wrongdoing will not be making vital decisions concerning the Welfare of the United States of America!”
Here’s a quick explainer on who Lisa Cook is, why Trump wants her gone and why her case could have enormous implications for the American economy.
Who is Lisa Cook?
Cook is an American economist who has been a member of the Fed’s board since May 23, 2022. She is the first woman of color to sit on the board. She was appointed by then-President Joe Biden and confirmed by the Senate by a 51-50 vote (with then-Vice President Kamala Harris breaking the tie). No Republicans voted to confirm Cook.
At the time, Republicans accused Cook of being “hyper-partisan,” pointing to her Twitter history as evidence.
Cook was educated at Spelman College, Oxford University and the University of California at Berkeley before serving as a professor at Harvard University and Michigan State University. She is considered an expert on international economics, especially the Russian economy and the economic history of African Americans.
Cook’s term on the Fed board runs until January 2038.
What is Cook being accused of?
In a letter dated Aug. 15, Federal Housing Finance Agency Director Bill Pulte, a Trump appointee who has since become the acting director of national intelligence, urged then-Attorney General Pam Bondi to investigate a pair of mortgages Cook took out in 2021.
The first, dated June 2021, was for a property in Ann Arbor, Mich.; according to Pulte’s letter, the terms of the mortgage stipulated it would be Cook’s primary home address for at least a year.
The second, taken out a few weeks later, was for a property in Georgia, which Cook also listed as her primary home address, according to Pulte.
Primary residence mortgages typically mean a lower interest rate, a lower down payment and a lower credit score to qualify; mortgage loans for a second home usually cost more and are harder to get. Buyers generally aren’t allowed to simultaneously claim two primary residence mortgages.
At Pulte’s request, the Justice Department opened a criminal investigation of Cook. But so far, she has not been charged with wrongdoing or convicted of a crime. In fact, financial documents dating from 2021 and reviewed by multiple media outlets in September 2025 show that Cook listed her Georgia residence as a “vacation home” and a “2nd home,” contradicting Pulte’s allegations.
“The fraud allegation is dramatically weakened by the evidence that this was on her application,” Kathleen Engel, an expert on mortgage fraud at Suffolk University’s law school, told the New York Times. “She was candid about how she was using the property.”
“It actually rebuts any inference that [Cook] engaged in fraud,” Engel added.
Meanwhile, Ann Arbor authorities told Reuters last year that they have “no reason to believe” that Cook violated the city’s property tax rules.
Why Trump can’t fire Cook — for now
The Federal Reserve was specifically designed by Congress to be shielded from political influence, since it often makes enormously important decisions about the direction of the economy that may not necessarily align with the interests of the sitting president. The only way for Trump to fire a Fed governor is “for cause,” according to the Federal Reserve Act of 1913. That standard has usually been interpreted to mean dereliction of duty or malfeasance, but it may change as the case moves through lower courts.
“Long tenures and removal protections for governors serve as a vital safeguard, ensuring that monetary policy decisions are based on data, economic analysis, and the long-term interests of the American people,” the Federal Reserve wrote in a statement in August 2025.
In her lawsuit, Cook said Trump had violated her right to due process, giving her no chance to respond to the allegations before announcing her termination. She also framed the firing as purely political — an attempt to oust a policymaker who wasn’t inclined to follow Trump’s calls to lower interest rates.
The Supreme Court agreed with Cook in its ruling on Monday, calling the administration’s attempt to claim it had given Cook proper due process “halfhearted.”
During oral arguments on the case in January, Justice Amy Coney Barrett, another Trump appointee, noted “the potential economic consequences of threats to the Fed’s independence, saying that those ramifications could play into the public interest in the outcome of Cook’s case,” according to Politico. And Justice Samuel Alito — one of the court’s most conservative members — questioned the “hurried” nature of the case, which has proceeded without a substantive review of the fraud allegations.
Alito and Barrett ultimately ruled in Trump’s favor on Monday but were in the minority.
Experts have warned that firing Cook could spell “the end of central bank independence as we know it,” as Peter Conti-Brown, a professor at the Wharton School of the University of Pennsylvania, put it last year.
Why is Trump at odds with the Federal Reserve?
The president has repeatedly argued that the Federal Reserve has undermined the U.S. economy by declining to lower interest rates as quickly as he would like. The Fed has opted to take a slow approach to rate reductions during Trump’s second term in order to keep inflation from rising.
Most of Trump’s ire had been directed at former Chair Jerome Powell, who led the Federal Reserve for eight years until his term ended last month. The Trump administration had also targeted Powell through a criminal investigation centered around his handling of renovations at the Federal Reserve’s headquarters and congressional testimony about its costs.
The administration dropped the case in April after key senators said they would refuse to confirm Powell’s successor if the investigation was still active. Trump’s pick to replace Powell as Fed chair, Kevin Warsh, was confirmed in late May.
