If you are a bank regulator, it might be a good idea to come to Sen. Elizabeth Warren's hearing knowing what you are getting into. Otherwise this happens. It starts getting really good around 1:40. At 2:30, the regulators say something baffling. And at 3:25, the senator expresses her disappointment with her usual eloquence.
Totally up to you, but I'm pretty sure the senator would appreciate you sharing this.
