A federal judge on Tuesday approved the proposed $26 billion T-Mobile and Sprint merger. The Justice Department and the Federal Communications Commission last year signed off on combining the third and fourth largest wireless carriers in the U.S., but the deal faced a lawsuit from state attorneys general. New York Attorney General Letitia James (D) last year called the merger “exactly the sort of consumer-harming, job-killing mega merger our antitrust laws were designed to prevent.” On Tuesday, U.S. District Court Judge Victor Marrero ruled that the merger wasn’t likely to “substantially lessen competition.” The companies say they need to join forces to compete and deliver new 5G service. The California Public Utilities Commission will still need to approve the merger. [The Washington Post]
