The case bears directly on Federal Reserve independence—a foundational principle of U.S. monetary policy. If Trump succeeds in removing Cook and appointing her replacement, he could control a majority of the Fed’s board and direct interest-rate policy, affecting borrowing costs and economic conditions for millions of Americans.
Supreme Court Questions Trump’s Authority to Remove Fed Governor
The Supreme Court on Wednesday heard arguments on whether President Donald Trump can force Federal Reserve Governor Lisa Cook from her post based on mortgage fraud allegations she denies, with at least six of the nine justices expressing skepticism about the constitutionality of the effort.
No president has ever fired a sitting Federal Reserve governor in the institution’s 112-year history. The Federal Reserve was deliberately structured to shield monetary policy from direct presidential control and daily political pressure.
“Allowing Cook’s firing to go forward would weaken, if not shatter, the independence of the Federal Reserve,” Justice Brett Kavanaugh, one of three Trump appointees on the court, said during Wednesday’s oral arguments. Chief Justice John Roberts also indicated skepticism, suggesting that the court should issue a broader ruling rather than merely returning the case to lower courts.
The Case Against Cook
Trump’s effort to remove Cook centers on allegations that she claimed two properties—one in Michigan and one in Georgia—as primary residences on mortgage applications submitted in June and July 2021, before she joined the Federal Reserve board. Such claims can lead to lower mortgage rates and smaller down payments. Trump’s solicitor general argued the applications showed “gross negligence at best.”
Cook has denied any wrongdoing and faces no criminal charges. Her lawyer, Abbe Lowell, wrote that “there is no fraud, no intent to deceive, nothing whatsoever criminal or remotely a basis to allege mortgage fraud.”
Justice Amy Coney Barrett suggested giving Cook a chance to respond to the allegations would be reasonable. Chief Justice Roberts and Justice Sonia Sotomayor, both of whom own multiple residential properties, expressed sympathy for Cook’s position. Sotomayor recalled her own experience: when she moved to Washington for her Supreme Court appointment, she had renovated her apartment the year before, assuming she would remain in New York. “Things change,” she said.
Trump’s Interest-Rate Agenda
Critics argue Trump’s real motivation is gaining control over monetary policy. If he succeeds in removing Cook and appointing a replacement, he would control a majority of the Federal Reserve’s board, giving him direct influence over interest-rate decisions that affect borrowing costs for mortgages, auto loans, and other consumer credit.
The Federal Reserve’s board cut a key interest rate three times in the last four months of 2025, but Trump has argued the reductions are insufficient. During a speech in Davos, Switzerland on Wednesday, Trump reiterated his call for aggressive rate cuts, stating the United States should pay “the lowest interest rate of any country in the world.”
The Fed, meanwhile, suggested it may hold rates steady in coming months due to inflation concerns, contradicting Trump’s stated preferences.
The Wider Confrontation
Trump is also pressing the Federal Reserve on other fronts. The Justice Department has opened a criminal investigation into Federal Reserve Chairman Jerome Powell and served the central bank with subpoenas. The disputes officially concern Powell’s testimony to Congress in June regarding costs for a Fed building renovation.
Powell responded sharply, calling the threat of criminal charges “pretexts” that mask Trump’s actual frustration over interest rates—a rare public pushback from the traditionally cautious central banker.
Cook and Powell both attended the Supreme Court arguments, which lasted nearly two hours.
The Supreme Court is expected to issue its decision by early summer.
