Sen. Elizabeth Warren has another complaint about Wells Fargo. This week, the Massachusetts Democrat and 2020 presidential candidate is taking issue with the bank allegedly charging fees on accounts that customers had believed to be closed. Warren has long criticized Wells Fargo for deceptive practices, as well as the leadership of former CEO Tim Sloan. In her latest letter, directed to interim CEO and President C. Allen Parker, Warren wants statistics on closed accounts, as well as whether the bank had, "any mechanism to catch fraudulent charges to these accounts" in order to avoid overdrafts being charged to accounts that were not supposed to exist.
