Elizabeth Warren called on JPMorgan Chase CEO Jamie Dimon to resign from his post on the Federal Reserve Bank of New York's board, citing the need for "responsibility and accountability" in the financial industry. Dimon, who disclosed a $2 billion loss by the banking giant last week, should "send a signal to the American people that Wall Street bankers get it and to show that they understand the need for responsibility and accountability," Warren said in a statement following Dimon's Sunday appearance on "Meet the Press."During that interview, Dimon said he "absolutely" believed that the enormous loss would give regulators more ammunition against the banks.
