Sprint has received subpoenas from Arizona, Florida, Hawaii, Illinois, Minnesota, New York, Pennsylvania, Texas and Washington regarding its opposition of AT&T’s planned $39 billion T-Mobile USA acquisition, Reuters reported on Tuesday. The U.S. Department of Justice’s antitrust division also issued a subpoena. Sprint has been a staunch opponent of the deal and its CEO Dan Hesse has said the acquisition will “stifle innovation” in the U.S. wireless market. He also said that “clearly, purely, [Sprint wants] to win and block the merger,” when it was revealed that Hesse was working with 18 state regulators to block the acquisition. The deal is getting an in-depth investigation from both the Department of Justice and the Federal Communications Commission. On June 22nd, AT&T’s General Counsel Wayne Watts said that the acquisition was on schedule for approval in March of next year. An AT&T spokesperson told Reuters that AT&T also received the same nine subpoenas.
