The head of TikTok's US security will appear before the House China committee on September 15.

      Will Farrell, the chief security officer for TikTok’s US operations, is set to appear before the House Select Committee on the Chinese Communist Party on September 15 to address questions concerning Beijing’s influence over the app, as reported by Reuters. He will be the first executive from the company, which has recently been sold to a group of US investors, to testify since the ownership transition was completed in January.

      The committee, led by Republican John Moolenaar, plans to question Farrell regarding data privacy issues and the extent of control that ByteDance, TikTok’s Chinese parent company, still has over the American operation. These questions have been raised prior to any attempts to ban TikTok, and the restructuring has not resolved them.

      Under a deal facilitated by President Donald Trump, ByteDance holds a 19.9% stake in the US operation, while daily control is now in the hands of a new entity named TikTok USDS Joint Venture LLC. Above this entity are three managing investors: the software company Oracle, private-equity group Silver Lake, and the Abu Dhabi investment firm MGX, according to the terms that have been disclosed thus far.

      This structure was designed to comply with a 2024 law that required ByteDance to sell TikTok or face a shutdown in the US. With approximately 170 million Americans using the app, a complete shutdown would have presented significant political challenges from the beginning. The 19.9% ownership was intentionally set just below the 20% threshold defined by the law for foreign adversary control.

      The Supreme Court upheld this law in January 2025, resulting in TikTok temporarily going offline before Trump, upon returning to office, issued a series of orders to pause enforcement while a buyer was sought. Each extension provided additional time, allowing the app to remain operational throughout. The divestiture did not actually conclude until this January, a full year after the initial deadline.

      What has practically changed due to the deal is only partially visible. Limited operational details have been shared, and the committee, led by Moolenaar, aims to clarify where American user data is stored. This question also relates to a data-transfer dispute TikTok faced in Europe.

      As the US security officer, Farrell is central to this matter, overseeing the systems designed to keep American user data away from ByteDance's reach in China, which is the technical assurance upon which the entire agreement depends. Notably, Adam Presser, TikTok’s US chief executive, is not expected to appear at the September hearing. Moolenaar had previously expressed a desire for the joint venture's leadership to testify in a public session this year, making Farrell's narrower role less comprehensive than he had initially hoped for.

      The Select Committee has been the most vocal body in Congress regarding Chinese technology, arguing for the past two years that ByteDance’s remaining stake, however minor, maintains a link back to Beijing. This hearing comes at a time when there is increased interest in TikTok's operations. Separately, Chuck Grassley’s Senate Judiciary Committee invited Shou Zi Chew, TikTok’s global CEO, to a June hearing focused on children's online safety, presenting a different line of scrutiny compared to Moolenaar's national-security concerns.

      TikTok is now facing inquiries from both committees in close succession. The company has consistently maintained that Chinese authorities cannot access American user data, a point reiterated during congressional hearings, legal disputes, and amidst this corporate restructure, which altered ownership without resolving the matter. Meanwhile, TikTok has been cutting costs in other areas, including job reductions at its Dublin hub this year, while investing heavily to validate the effectiveness of the new American structure.

      Neither TikTok nor the committee has shared Farrell's prepared statements, and details regarding which documents TikTok plans to provide remain undisclosed.
