Jamie Dimon himself called to urge support for the derivatives rule in the spending bill 11 Dec 2014 The acrimony that erupted Thursday between President Obama and members of ‘his own party’ largely pivoted on a single item in a 1,600-page piece of legislation to keep the government funded: Should banks be allowed to make risky investments using taxpayer-backed money? The very idea was abhorrent to many Democrats on Capitol Hill. And some were stunned that the White House would support the bill with that provision intact, given that it would erase a key provision of the 2010 Dodd-Frank financial reform legislation, one of Obama’s signature achievements. But perhaps even more outrageous to Democrats was that the language in the bill appeared to come directly from the pens of lobbyists at the nation’s biggest banks, aides said. The provision was so important to the profits at those companies that J.P.Morgan’s chief executive Jamie Dimon himself telephoned individual lawmakers to urge them to vote for it, according to a person familiar with the effort.
