The ongoing debate over TikTok's future in the US.

U.S. lawmakers are set to move forward with legislation to address national security concerns about TikTok, alleging that China's government has access to the app's user data. TikTok CEO Shou Zi Chew appeared before a U.S. House Committee for about five hours on Thursday, and lawmakers from both parties grilled him about national security and other concerns involving the app, which has 150 million American users. The company says it has spent more than $1.5 billion on data security efforts under the name "Project Texas" which currently has nearly 1,500 full-time employees and is contracted with Oracle Corp to store TikTok's U.S. user data.
