Citigroup and JP Morgan Chase had huge investment banking arms well before the financial crisis. What do you think the "JPMorgan" part of "JPMorgan Chase" does? Why do you think "group" part of "Citigroup" does?
Yes, and JP Morgan Chase was still in relatively good financial shape compared to the other firms. People will argue they still never really needed a bailout. With Citigroup you have a point.
