According to Mars Finance news, on August 28, former U.S. Treasury Secretary Yellen commented on the controversy surrounding Trump's firing of Federal Reserve Governor Cook, stating: Trump claims to have 'fired' Cook for 'cause,' a move that is not only illegal but also poses great danger. This is a direct attempt to politicize the Federal Reserve, an intimidation of its leadership, and an effort to force monetary policy to submit to the president's will. This action could end the independence of the Federal Reserve — and with it, the collapse of the credibility of U.S. monetary policy both domestically and internationally. Yellen called on Congress to defend the independence of the Federal Reserve, the courts must reject this illegal abuse of power, and the financial community must speak out against this direct attack on the credibility of the dollar.
