Woofun AI reports that U.S. Senator Elizabeth Warren has called on Federal Reserve Governor Christopher Waller to stop his initiative to restructure the 12 regional Federal Reserve Banks. As the senior Democrat on the Senate Banking Committee, Warren stated in a letter on Wednesday that the proposed changes may violate federal law and threaten the central bank's independence. Although Waller chairs the Reserve Bank Affairs Committee, the regional banks retain significant operational autonomy. Warren characterized the proposal as an attempt to appease President Trump regarding control over regional leadership. She demanded Waller immediately halt all related activities and provide further details to Congress.
