• The Senate Homeland Security and Governmental Affairs Committee will hold a hearing on the influence of social media on homeland security.
• A Facebook or Meta executive will be testifying before Congress for the 31st time in the previous five years.

The United States Senate Homeland Security and Governmental Affairs Committee will hold a hearing Wednesday on the influence of social media on homeland security with Facebook parent Meta Platforms (META.O), Alphabet’s YouTube (GOOGL.O), Twitter (TWTR.N), and short video app TikTok.

A panel of former executives, including those from Twitter and Facebook, will also speak before the committee chaired by Democratic Senator Gary Peters.

The hearing will provide an opportunity, according to the committee, “to understand the extent to which social media companies business models, through algorithms, targeted advertising, and other operations and practices, contribute to the amplification of harmful content and other threats to homeland security.”

The witnesses from the company, including Meta, Neal Mohan, Chief Product Officer of YouTube, Chris Cox, Vanessa Pappas, Chief Operating Officer of TikTok, and Jay Sullivan, General Manager of Bluebird at Twitter.

A Facebook or Meta executive will be testifying before Congress for the 31st time in the previous five years.

Last year, Peters urged social media companies for additional details about their companies’ procedures for identifying and removing violent extremist and conspiratorial content.

Peters has examined the ways in which social media sites promote what he called “domestic extremist content.”

At a 2021 hearing, Peters stated that “In attack after attack, there are signs that social media platforms played a role in exposing people to increasingly extreme content, and even amplifying dangerous content to more users.”
