In a contentious hearing on Wednesday, the CEOs of Facebook (FB
), Google (GOOG
) and Twitter (TWTR
) were questioned by Senators on the Commerce Committee over their content moderation policies. Some lawmakers demanded more transparency while others sought explanations on a few specific cases in which content was removed or labeled by platforms. Though the hearing was meant to focus on a crucial law, known as Section 230, that protects the companies’ ability to moderate content as they see fit, Senators strayed from the brief and confronted the executives on other topics, including antitrust, misinformation about voting and election interference.
