Facebook CEO Mark Zuckerberg, Google CEO Sundar Pichai and Twitter CEO Jack Dorsey testified on social media content moderation before the Senate Commerce, Science and Transportation Committee. The social media companies are accused by conservatives of censoring conservative viewpoints. Democrats want the tech CEOs to do more to stop the spread of “misinformation” and content that could incite violence. Many committee members focused on Section 230 of the Communications Decency Act, which shields social media companies from liability for content posted on their sites and affords them wide latitude in content moderation. This is the second portion of the hearing, after the committee returned from a short recess.
