Accounting firm PWC nailed for whitewashing banking client's sanctions violations; Fined $25M

``Regulators say PwC changed the warning language in a report it submitted for its client, Bank of Tokyo Mitsubishi. The language originally pointed out that the Japanese bank had done wire transfers on behalf of countries that face U.S. sanctions, such as Iran and Sudan. But, after pressure from the bank , the language was whitewashed so it was less likely to trigger red flags with regulators.''
