Former Facebook executive Sarah Wynn-Williams accuses Meta of colluding with China and undermining U.S. national security.
Wynn-Williams claims Meta created custom-built censorship tools for the CCP, granting them significant power over content moderation.
Meta denies the allegations, stating that they do not currently operate their services in China and Wynn-Williams' testimony contains false claims.
Wynn-Williams also shared documents indicating Facebook executives discussed granting the Chinese government access to user data from China and Hong Kong.
