Following a year plagued by regulatory headaches, JPMorgan Chase CEO Jamie Dimon's wallet got even fatter—a move that Sen. Elizabeth Warren, D-Mass., questioned Thursday.
For 2013, Dimon was awarded a 74-percent pay raise to $20 million by the bank's board even as it grappled with billions in penalties and settlements.
"Jamie Dimon got a raise after he negotiated $17 billion to pay for activities that were illegal that he presided over. So I'm not quite sure how this is a deterrent for other CEOs," Warren said during a Senate Banking Committee hearing.
During the year, JPMorgan's stock surged nearly 31 percent, slightly outpacing the rise in the S&P 500.
