Key staff members at the U.S. Federal Trade Commission were in favor of suing Google Inc for violating antitrust rules before the agency settled its investigation in 2013, according a confidential report cited by the Wall Street Journal on Thursday. The report by the staff of the FTC’s competition bureau argued that the owner of the world’s No. 1 Internet search engine illegally took information from rival websites to improve its own search results and placed restrictions on websites and advertisers. The report recommended suing Google for several of its business practices.
