The CEOs of Meta, TikTok, X and other social media companies have testified before the Senate Judiciary Committee about child safety on their platforms.

A Senate committee has issued bipartisan subpoenas to the CEOs of Discord, Snap and X, demanding that the heads of the three companies testify at a December hearing on protecting children online.

The parent company of social media platform Snapchat said Wednesday that it is letting go of 20% of its staff as it reorganizes and tries to reduce costs in the face of declining sales.
