President Trump is making a second attempt to remove Federal Reserve Governor Lisa Cook from her position, 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 ever 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. 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. 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 rules for a Fed governor this way.

Here is why this matters. The Federal Reserve is the central bank of the United States. It sets a key interest rate called the federal funds rate, which is the rate banks charge each other for overnight loans. That rate acts like a dial for the whole economy. When the Fed turns it up, borrowing gets more expensive — mortgages, credit cards, car loans. When the Fed turns it down, borrowing gets cheaper and savings accounts pay less interest.

The people who set that rate are the members of a group called the Federal Open Market Committee, or FOMC. Cook is one of the voters on that committee. So removing her would directly change who gets a say in setting interest rates for the entire country.

The law that created the Federal Reserve gives governors 14-year terms. Those long, staggered terms are designed so that no single president can pack the Board with allies all at once. The law says a governor can only be removed "for cause," which has historically meant clear misconduct or neglect of duty — not a disagreement over policy. Cook's legal team argued that the mortgage fraud allegations did not meet that standard and were invoked after the fact to justify a removal Trump had already decided on.

Cook, the first Black woman to serve as a Federal Reserve governor, joined the Board in 2022.

The Supreme Court's 5-4 split means the legal question is far from settled. A one-vote margin on something this important gives the executive branch reason to believe a second attempt, using different arguments, might work.

The details of Trump's new effort are not yet known. But pressing forward after a Supreme Court loss adds strain to an already difficult period for the Federal Reserve. The central bank's credibility depends on the public believing its decisions are based on economic data and professional judgment, not political orders. An ongoing public fight between the White House and a sitting governor does not help that perception.

In my view, the practical question for everyday savers and borrowers is whether this fight injects uncertainty into the Fed's interest-rate decisions. Governors are not easily replaced. Even if a removal eventually succeeded, the Senate confirmation process for a replacement would take months. That could leave the Board short-handed at a time when interest-rate decisions carry unusually high stakes. A committee with fewer members still sets rates, but the range of debate narrows and close votes become 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 a confrontation the central bank would prefer to have resolved.
