Steve Mnuchin, Treasury Secretary in the Trump administration, said Tuesday he is still interested in buying TikTok from ByteDance, which has ties to the Chinese Communist Party.

He also said the controversial social media apps' algorithm could be rebuilt if the Chinese government bars ByteDance from selling it. ...

"I've actually spoken to a lot of tech companies on working about rebuilding this," Mnuchin told Bloomberg Television on Tuesday. "I do believe the algorithms could be rebuilt. So, my plan, if we were to purchase, it would be to rebuild the technology under U.S. leadership, make sure that it's all disconnected from ByteDance going forward, and that it is very robust and secure."
