WARREN: Did you see the headline? One of America's biggest banks lost $2 billion in just a few weeks. Even now, Wall Street banks that got bailed out are still at it, gambling recklessly. This is Elizabeth Warren. I stood up to big banks. I took on their army of lobbyists and helped win the fight for a consumer protection agency. But there's still more to do. Wall Street isn't going to change its ways until Washington gets serious about strong oversight and real accountability. No special deals. We need a tough cop on the beat to make sure that nobody steals your purse on Main Street or your pension on Wall Street. Problem is, in Washington money talks -- and Wall Street has plenty of money to spread around. So Wall Street gets all the special breaks while working families get hammered. That's what I want to change.
