The White House has revived its efforts to remove Lisa Cook, the first Black woman to serve as a governor at the Federal Reserve, the United States’ central bank. On Friday, media reports emerged that the administration of President Donald Trump had sent Cook a letter threatening her position at the Federal Reserve. Her conduct, the letter added, constituted negligence that calls into question her trustworthiness as a Federal Reserve governor. No other president since the central bank’s founding in 1913 has sought to oust a Federal Reserve governor. Trump has long sparred with the Federal Reserve over interest rates, repeatedly threatening to fire former Federal Reserve Chair Jerome Powell for refusing to bow to his demands.
