A US senator lambasted Wells Fargo and Co.'s CEO John Stumpf over his involvement in the unauthorized opening of over 2 million accounts to meet sales targets. Massachusetts Democrat Senator Elizabeth Warren said Stumpf should resign and be criminally investigated by both the Department of Justice and the Securities and Exchange Commission. Democrat Senators in unison demanded greater accountability from the company. As calls for the stepping down of Wells Fargo and Co.'s CEO John Stumpf grew louder, sources revealed that he may be entitled to a $200 million severance payout. Sources added that the $200 million would include cash and stocks, and even if Stumpf is fired, he would forfeit only a small portion. Wells Fargo has declined to comment on the matter. CEO John Stumpf could not address direct questions posed to him in court. He failed to respond when asked how Wells Fargo sought to compensate customers whose credit risk ratings may have been affected by the scandal. While Stumpf apologized for the measures taken by the company, he refused to hold himself accountable for the scandal to Wells Fargo shareholders. In the wake of the fake account creation scandal, Wells Fargo announced that their CEO John Stumpf would retire, effective immediately. Inside sources stated that the decision was taken by Stumpf himself and that it was welcomed by the company's Board of Directors. Investigations into the scandal are ongoing and Stumpf's role in the matter will be closely looked at.
