Citigroup CEO Vikram Pandit resigns:
Citigroup Chief Executive Vikram Pandit has resigned, effectively immediately, a shock change at the top of the bank just one day after surprisingly strong quarterly results.
Vikram Pandit denied that he was forced out as Citigroup's CEO, telling CNBC Tuesday that it was his decision to step down after five years at the bank and that he had been thinking about it for awhile.
