Wells Fargo's scandal reportedly impacted 10,000 small business accounts

Wells Fargo's recent accounts scandal was not limited to its retail banking unit, according to a report from Reuters.

Citing sources familiar with the matter, 10,000 small business accounts were impacted by Wells sales practices that also drove employees to open 2 million retail accounts without the knowledge of customers. It was not clear in the Reuters report how the small business accounts were impacted.

In a letter to Wells Fargo CEO John Stumpf on September 29, Sen. David Vitter claimed that the scandal went beyond the retail sector, according to Reuters.

Stumpf was asked during his testimony to the House Financial Services Committee on Thursday whether the accounts scandal impacted the small business division of the bank. He responded that he was not aware that it had spread.
