TikTok’s head of security is scheduled to testify before the US House Select Committee on the Communist Party of China on September 15.

The appearance marks a significant escalation in congressional scrutiny of the short-video platform’s data handling and cybersecurity protocols.

The executive, who oversees data privacy and cyber defense for the company, will face questioning from lawmakers regarding the platform’s operational security and its relationship with its Chinese parent company, ByteDance.

The hearing comes as US legislators intensify their focus on national security risks associated with foreign-owned social media platforms.

This development follows a period of heightened regulatory activity for TikTok across multiple jurisdictions.

The company has recently pushed back against European Union efforts to restrict children’s access to social media, with its policy chief defending existing safety measures as adequate.
