The head of Wells Fargo is apologizing to Congress for his bank setting up fake accounts.

FOX's Jared Halpern has more from Capitol Hill:

Wells Fargo CEO John Stumpf says he takes responsibility for employees setting up accounts and credit cards for customers without consent to hit sales targets:

(Stumpf) "Goes against everything regarding our core principles, our ethics and our culture."

More than 5,000 Wells Fargo employees were fired and the bank was fined $185 million, but Senate Banking Committee Democrat Elizabeth Warren says that's not enough:

(Warren) "You should resign. You should give back the money you took while this scam was going on and you should be criminally investigated."
