sentences:  In advance of his March 8 speech to the Conservative Political Action Conference, Fisher proposed requiring breaking up large banks into smaller banks so that they are "too small to save", advocating the withholding from mega-banks access to both Federal Deposit Insurance and Federal Reserve discount window, and requiring disclosure of this lack of federal insurance and financial solvency support to their customers.This was the first time such a proposal had been made by a high-ranking U.S. banking official or a prominent conservative.Other conservatives including Thomas Hoenig, Ed Prescott, Glenn Hubbard, and David Vitter also advocated breaking up the largest banks, but liberal commentator Matthew Yglesias questioned their motives and the existence of a true bipartisan consensus.
