FTC building Google case: The Federal Trade Commission is preparing a recommendation to sue Google for its search practices, the New York Times reported, citing a draft reportedly being shared with FTC commissioners.

FTC chairman John Leibowitz said last month that the agency will make its final decision about whether to sue the search engine giant by the end of the year.

On Friday, Rep. Jared Polis (D-Colo.) urged the FTC not to sue Google for antitrust violations, The Hill reported. that Polis, who has a background in Internet companies, said that he believes the search market is competitive and that applying anti-trust regulations to Google “defies all logic and the very underpinnings of anti-trust law itself.”
