The Justice Department said on Thursday it would appeal a federal judge’s approval of AT&T’s merger with Time Warner, extending the government’s legal challenge of the blockbuster deal.
A federal judge signed off on the deal a month ago, saying the federal agency did not sufficiently prove that the merger would harm competition and consumers.
The companies have moved forward with their $85.4 billion agreement, putting an AT&T executive in charge of the media conglomerate that produces HBO hit shows like “Game of Thrones” and the news network CNN.
AT&T and Time Warner executives have said they were confident they would win an appeal of the merger because of the judge’s sweeping rejection of the government’s case.
