'Our (lawyers) sent a formal request to Bloomberg to verify exactly what information reporters had access to and confirmation of their controls to prevent future breaches', a bank spokeswoman said.
The request, sent in recent days, amps up pressure on Bloomberg to fork over specific information about its past practice of its reporters using the firm’s namesake data terminals to keep tabs on clients, including JPMorgan and Goldman Sachs.
The Financial Times reports that people at the bank said it had demanded 'logs of all Bloomberg staff who have looked up JPMorgan users and usage since the beginning of 2008 and the role of people who ran each query'.
The bank’s lawyers also demanded verification that Bloomberg had revoked reporters’ access to information about terminal users.
