When it merged with Citi, that became a big issue; Citi, at that time, wasn't yet a fully integrated, coordinated company.

A lot of these things have hurt the average American. When they look at the banks and they say, "Well, the bank's talking its own game," I am telling you, what we've done in mortgage lending, our inability to have proper regulations around mortgages, has hurt average Americans.
