Facebook chief Mark Zuckerberg responded to accusations from President Trump that the social network has always been "anti-Trump," defending the company he founded while acknowledging that he shouldn't have shaken off concerns about Facebook's influence.

Trump said on Twitter Wednesday that Facebook and news media — including The Washington Post — had always been opposed to him. Zuckerberg said that the fact that Facebook fields criticism from Trump as well as liberals shows it's a "a platform for all ideas."
