A screen displays JP Morgan Chase & Co. at the post that the stock is traded at on the floor of the New York Stock Exchange, October 21, 2013. JPMorgan Chase & Co CEO Jamie Dimon has pleaded with and complained to the U.S. Justice Department but cannot convince the government to end its criminal probe of his bank because prosecutors are not yet certain of their findings, people familiar with the matter said. Dimon has negotiated a tentative $13 billion deal to settle many of the U.S. investigations into mortgage bonds that JPMorgan - and the banks it bought during the financial crisis - sold to investors.
