In a Senate Banking Committee haering last week, Senator Elizabeth Warren was unrelenting in her questioning of Wells Fargo CEO John Stumpf, who was giving testimony on the bank's fraudulent practice of opening unauthorized accounts for customers in order to help meet sales goals.

Sen. Warren is an ardent champion of policies that protect everyday Americans from bilking at the hands of wealthy special interests, especially those in the financial sector. In her questioning, Warren called out Stumpf for making millions of dollars in the Wells Fargo scam, and for showing "gutless leadership" by refusing to resign, fire any senior executives, or even return any of his earnings.

Warren said:

This is about accountability. You should resign. You should give back the money that you took while this scam was going on, and you should be criminally investigated by both the Department of Justice and the Securities and Exchange Commission. This just isn't right.
