U.S. Federal Communications Commission Chairman Tom Wheeler has announced that he will leave the agency he helmed for the past three years on Jan. 20, the day President-elect Donald Trump will be sworn in. “Serving as FCC chairman during this period of historic technological change has been the greatest honor of my professional life,” Wheeler said. “It has been a privilege to work with my fellow commissioners to help protect consumers, strengthen public safety and cybersecurity, and ensure fast, fair and open networks for all Americans.”
