Sen. Sanders gathers economists for his planned Fed overhaul bill

While the economists have agreed to offer their thoughts to Sanders, it is not clear exactly how those recommendations will come back, according to Sanders's office. They may come together for a meeting, or simply each offer a list of recommendations.

Sanders announced he was tapping economists for advice on reforming the Fed after a study from the Government Accountability Office said that the Federal Reserve banks should be more transparent about directors who have ties to the financial sector.

Rep. Dennis Kucinich (D-Ohio), another left-leaning critic of the Fed, got in on the action Thursday, using the report to criticize the central bank.

"The Federal Reserve operates with brazen disregard for the best interests of the American economy and with very serious conflicts of interest,” he said.
