When asked if its Chinese owners would divest if instructed by the U.S. Treasury, TikTok CEO Shou Zi Chew responded, "it's not about the ownership," adding, " American social companies don't have a good track record with data privacy and user security. I mean, look at FaceBook and Cambridge Analytica."

TikTok has said it has spent more than $1.5 billion on what it calls rigorous data security efforts under the name "Project Texas" that currently has nearly 1,500 full-time employees and is contracted with Oracle Corp to store TikTok's U.S. user data. It also says it strictly screens content that could harm children.
