WASHINGTON (AP) — Sen. Elizabeth Warren says Wells Fargo’s CEO should be criminally investigated by the Justice Department and securities regulators over allegations that bank employees opened accounts without customer permission to meet sales quotas.

The Massachusetts Democrat, one of the fiercest critics of Wall Street, challenged John Stumpf about what he has done regarding his repeated claim of being accountable. She asked whether he had returned “one nickel” of what he was paid while the conduct went on or had fired any senior executives. She said, “It’s gutless leadership.”

She told Stumpf he should resign and “give back the money you took while the scam was going on.”

Regulators fined San Francisco-based Wells Fargo $185 million earlier this month.
