Facebook CEO Mark Zuckerberg, Twitter CEO Jack Dorsey and Google CEO Sundar Pichai will testify before Congress on Oct. 28, reports CNET.
The US Senate's Commerce committee had voted unanimously to subpoena the appearances of Zuckerberg, Pichai and Dorsey, but the CEOs agreed to appear without being subpoenaed, according to The Washington Post.
The hearing will be called "Does Section 230's Sweeping Immunity Enable Big Tech Bad Behavior?," the Senate committee said Friday. It relates to changes being considered to s230 of the 1996 Communications Decency Act, which is considered the most important law protecting speech online.
It prevents social media platforms, such as Facebook and Twitter, and internet providers, such as Verizon and Comcast, from lawsuits over posts made by users on their services.
The CEOs will be questioned on their companies' content moderation practices, how their platforms affect local journalism and consumer privacy, and "how best to preserve the internet as a forum for open discourse." It will be live streamed for the public.
