Carl Levin actually said...

"You don't believe it is relevant to a customer of yours that you are selling a security to that you are betting against that same security."

"Do you think if your people think something is a piece of crap and go out and sell that, and then your company bets against it, do you think that deserves your trust?"

"Thank you, Mr. Chairman, and, again, I congratulate you for this in-depth investigation."

"You are betting against the very product you are selling, and you are just not troubled by it."
