Unlike his former boss, the former Treasury secretary said he's supportive of a bipartisan bill that would ban the popular social-media app.

“I understand the technology,” Mnuchin said during an interview on CNBC’s “Squawk Box.” “It’s a great business, and I’m going to put together a great group to buy TikTok.”

While he declined to provide specific names, Mnuchin said that his group would be organized in a way “so that no one investor controls this.”
