Facebook, Twitter and Google CEOs return to Congress Thursday to address the spread of misinformation on their platforms.

In virtual appearances, the three executives plan to inform members of the House’s Energy and Trade Committee of the steps they have taken to combat the spread of false information about their services, particularly during the 2020 elections and the Covid-19 Pandemic. At stake is the legal shield protecting their platforms from being held liable for the contributions of their users, known as Section 230 of the Communications Decency Act.

Legislators of both parties broadly support updating the law to make the largest platforms more accountable for their moderation standards, although many disagree on exactly how to do it.

Facebook’s Mark Zuckerberg plans to make his own proposal based on his written testimony, which some members of Congress have already dismissed as selfish. Sundar Pichai, CEO of Google, plans to express his concern about the existing proposals to amend the basic Internet law.
