Big Wall Street banks are so upset with Democratic Sen. Elizabeth Warren's call for them to be broken up that some have discussed withholding campaign donations to Senate Democrats in symbolic protest, sources said.
Representatives from Citigroup, JPMorgan, Goldman Sachs and Bank of America have met to discuss ways to urge Democrats, including Warren and Ohio Sen. Sherrod Brown, to soften their party's tone toward Wall Street, sources said.
Bank officials said the idea of withholding donations was not discussed at a meeting of the four banks in Washington but it has been raised in one-on-one conversations between representatives of some of them. However, there was no agreement on coordinating any action, and each bank is making its own decision, they said.
