Sony has said it will answer questions put to the company by the US Congress, the United States' legislature for the federal government, regarding the PSN hack and breach of customers' personal information.
However, SCEA declined to testify at a Congressional hearing about the threat of data theft to American consumers "because their internal investigation is still ongoing", an official in Congresswoman Mary Bono Mack's office told Kotaku.
Earlier this week, a two page letter signed by Bono Mack, Republican of California, was sent directly to PlayStation boss Kaz Hirai requesting answers for a number of unanswered questions concerning the "outside intrusion" of the PlayStation Network.
Sony said in a statement: "Sony is cooperating with the request for answers to the Committee's questions, and in fact will be providing our responses in advance of the [May 6] deadline.
"We informed the committee that we could not appear as early as this Wednesday because of our ongoing intensive investigation and management of this criminal cyberattack."
