A House Financial Services Committee hearing Wednesday turned briefly to JPMorgan’s $2 billion loss in risky trading.
Bloomberg News reports that JP Morgan has deployed teams of representatives to brief congressional staffers about the trading strategy that led to the losses, which were first disclosed last week.
