JPMorgan takes legal measures in Bloomberg scandal

JPMorgan Chase is demanding Bloomberg LP cough up more information on the spying scandal, The Post has learned.

Legal eagles at the bank, run by Chief Executive Jamie Dimon, want assurances that the data giant has stopped snooping on clients. “Our legal department 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 JPMorgan spokesman said.

The request, which was sent in recent days, steps up the pressure on Bloomberg to offer more details on the remedies put in place to address the practice of reporters using namesake terminals to keep tabs on clients, including major firms such as JPMorgan and Goldman Sachs.

It comes on the heels of an apology tour of 300-plus clients by Bloomberg Chief Executive Dan Doctoroff. A person familiar with the bank’s thinking said it takes Bloomberg’s breaches very seriously.

Additional details JPMorgan are demanding include logs of all Bloomberg staff who have looked up JPMorgan Chase users and their usage since the beginning of 2008.

The bank also wants to know the roles of each individual who sought information about its employees. “We expect a prompt follow-up,” said one source.

A Bloomberg spokesman declined to comment.
