Corzine Traded Obsessively; Threatened Board With Quitting

[Corzine] pushed through a $6.3 billion bet on European debt -- a wager big enough to wipe out the firm five times over if it went bad -- despite concerns from other executives and board members. And it is now clear that he personally lobbied regulators and auditors about the strategy.

Mr. Corzine compulsively traded for the firm on his BlackBerry during meetings, sometimes dashing out to check on the markets. And unusually for a chief executive, he became a core member of the group that traded using the firm's money. His profits and losses appeared on a separate line in documents with his initials: JSC.
