That’s because Congress has wrongfully tied the president’s hands with respect to removing members of the Federal Reserve Board of Governors. This might explain why Trump, who’s made no secret of his displeasure with Powell, might have gone looking for criminal charges against Powell based on something Powell had done while in office. And Federal Reserve Governors don’t just set interest rates and control the money supply. If Congress doesn’t want the president to remove Fed Governors, then it should at least strip them of their regulatory and law-enforcement powers and place those responsibilities in another agency. And it should recognize in Cook’s case that his firing authority extends to Federal Reserve governors, too.
