Iowa Attorney General Tom Miller is joining a coalition of 38 attorneys general in suing Google. The antitrust case alleges Google illegally maintains its monopoly power over general search engines and related advertising markets through a series of anticompetitive exclusionary contracts and conduct. Miller says there’s one key thing he sees in the suit.

Iowa is also part of a lawsuit announced December 9th against Facebook, alleging the company broke the law by acquiring potential rivals and cutting smaller competitors off from its platform and services.
