Sen. Bernie Sanders (I-Vt.) introduced a bill Wednesday that would break up some of the largest U.S. banks, a long-standing goal of financial sector skeptics. The bill would force the federal government to dismantle any bank with total exposure greater than 3 percent of U.S. GDP, which is roughly equal to $584 billion. Banks above that threshold would be given two years to downsize before the federal government would be forced to take them apart.
