President Trump is making a second attempt to remove Federal Reserve Governor Lisa Cook from the Board, less than six weeks after the U.S. Supreme Court blocked his first effort in a 5-4 ruling on June 29, 2026.

No president had previously tried to remove a Federal Reserve governor the way Trump went after Cook. The Supreme Court's June 29 decision upheld lower-court rulings that had kept Cook in her seat throughout the litigation. A U.S. district judge first temporarily blocked the removal in September 2025, and lower courts consistently barred her ouster before the Supreme Court took up Trump's bid in January 2026.

Trump's initial attempt to fire Cook came in August 2025, when he cited unproven mortgage fraud allegations as grounds for removal. Cook denied the allegations. She then sued Trump and the Federal Reserve, arguing that the claims did not give the president legal authority to remove her and were a pretext. That lawsuit was the first time a sitting president tested the removal framework for a Fed governor in this way.

The legal question centers on protections built into the Federal Reserve Act. Governors serve 14-year terms, staggered so that one president cannot appoint the entire Board at once, which helps insulate monetary policy from political pressure. The statute says governors may be removed "for cause" — meaning demonstrable misconduct or neglect of duty, not simply a disagreement over policy. Cook's legal team argued that the mortgage fraud allegations Trump cited did not meet that threshold and were invoked retroactively to justify a removal already decided on other grounds.

Cook, the first Black woman to serve as a Federal Reserve governor, joined the Board in 2022. Her seat on the seven-member Board of Governors makes her one of the voting members of the Federal Open Market Committee (FOMC), the body that sets the federal funds rate target range. The federal funds rate is the overnight lending rate banks charge each other; it serves as the benchmark that influences interest rates across the economy, from mortgages to credit card APRs to savings account yields. A politically motivated removal would carry consequences well beyond institutional politics.

The Supreme Court's 5-4 split signals the legal question is far from settled. The narrow majority suggests the Court's reasoning may have turned on procedural grounds, on whether the specific allegations met the "for cause" standard, or on the broader separation-of-powers doctrine that has shielded independent agencies since Humphrey's Executor v. United States in 1935. A one-vote margin on a question of this magnitude gives a determined executive branch reason to believe a second attempt, built on different factual claims or legal arguments, might succeed.

The mechanics of Trump's renewed effort are not yet detailed, but the decision to press forward despite a Supreme Court loss introduces a new variable into what is already an unsettled period for Federal Reserve governance. The central bank's credibility rests in significant measure on the perception that its policy decisions reflect economic data and professional judgment, not political directives. An ongoing, public confrontation between the White House and a sitting governor, unresolved through two rounds of litigation, does not strengthen that perception.

The broader context here is what this means for markets and for anyone with a mortgage, credit card, or savings account. The practical question is whether the renewal of removal proceedings injects uncertainty into the FOMC's deliberative process. Governors are not easily replaced. Even if a removal eventually succeeded, the confirmation process for a successor would take months, potentially leaving the Board short-staffed during a period when monetary policy decisions carry unusually high stakes. An FOMC operating with fewer than its full complement of governors still sets rates, but the breadth of internal debate narrows, and the legitimacy of close votes becomes easier to question.

The lower courts have so far treated Cook's removal as impermissible. The Supreme Court, by a single vote, agreed. Trump's decision to try again does not change the law, but it does extend the duration of an institutional confrontation that the central bank would prefer to have resolved.
