(Reuters) – AT&T has asked regulators to let it ignore a shareholder request for details of its customer-information sharing with government agencies, a move that could forestall a heated debate at the telecommunications giant's annual meeting. The No. 2 U.S. mobile operator made the request in a December 5 letter to the U.S. Securities and Exchange Commission in response to shareholder activists pressing it on the matter. Among them is New York State Comptroller Thomas DiNapoli, who is the trustee of the state retirement fund. DiNapoli and other shareholders of AT&T and its biggest rival Verizon Communications Inc last month sought details on sharing of personal data and communications from the two companies following revelations from former U.S. National Security Agency contractor Edward Snowden.
