Trump plays to the base with attack on ‘rigged’ Google searches

"Any effort to regulate social media companies and search engines would run up against a bevy of constitutional free speech questions. Legally, Trump doesn’t have any authority to change how Google displays search results, said Daphne Keller, director of intermediary liability at the Stanford Center for Internet and Society.

“By dictating what a private company does with search results, it legally would be like dictating what The Chronicle does with news reporting,” Keller said. “It would be a First Amendment violation.”"
