All living former Fed chairmen signed a letter urging the Supreme Court to protect the independence of the Fed.

[All living former Federal Reserve Chairmen sign a letter urging the Supreme Court to protect the independence of the Fed] Major economic policymakers in the U.S. over the past 35 years, including all living former Federal Reserve Chairmen, are urging the Supreme Court to allow Federal Reserve Board of Governors member Cook to continue in her position. The amicus brief warns that allowing her to be removed while Cook's legal challenges are ongoing would signify a destructive erosion of the safeguards established by Congress 90 years ago to ensure the independence of the executive branch. The research cited by the signatories of this letter indicates that central banks can reduce inflation and lower long-term interest rates by not considering short-term political factors when setting interest rates. This briefing is signed by former Fed chairmen Alan Greenspan, Ben Bernanke, and Janet Yellen. The 18 signatories also include presidential advisors from both Republican and Democratic administrations, as well as leading economists from different ideologies: former Treasury Secretaries Robert Rubin and Lawrence Summers, former Chairman of the Council of Economic Advisers Glenn Hubbard and Greg Mankiw, among others.
