The head of the U.S. Federal Communications Commission does not expect to review AT&T Inc’s planned $85.4 billion acquisition of Time Warner Inc , a spokesman for the agency said on Monday. FCC Chairman Ajit Pai had told the Wall Street Journal in an interview on Monday at the Mobile World Congress in Barcelona that he did not foresee a role for the FCC on the takeover and his comments were confirmed to Reuters by FCC spokesman Neil Grace.
