Senate Democrats aim to ban proprietary trading at large banks

Sens. Carl Levin, D-Mich., and Jeff Merkley, D-Ore., proposed an amendment to the financial-reform bill that would prohibit proprietary trading at the largest banks. Opponents of the measure said it would restrict bank operations that didn't contribute to the financial crisis. They also said the proposal lacks flexibility for regulators to decide the best course of action for individual banks.
