Trump v. Cook

Donald J. Trump, et al. v. Lisa D. Cook is a lawsuit brought by Lisa Cook, a member of the Federal Reserve Board of Governors, against U.S. president Donald Trump, the board, and its chairman, Jerome Powell. Cook contended that her "for cause" removal, executed by Trump as president, was not justified.

On September 9, 2025, District of Columbia U.S. District Court Judge Jia Cobb issued a preliminary injunction preventing the firing of Cook, stating that "the Court finds that Cook has made a strong showing that her purported removal was done in violation of the Federal Reserve Act's 'for cause' provision." On September 15, the United States Court of Appeals for the District of Columbia Circuit rejected an emergency appeal by the Trump administration to remove Cook before the September 2025 meeting of the Federal Open Market Committee. On October 1, the Supreme Court rejected an emergency appeal filed by the Trump administration to remove Cook. Oral arguments were held in January 2026.
