During the Biden administration, Congress passed legislation forcing TikTok's parent company, ByteDance, to sell or be banned in the United States.

After Trump's inauguration, he extended the deadline to sell by 75 days.

Rasner, CEO of wealth management company Omnivest Financial, discussed his offer with NBC News on Thursday, saying the Trump administration has reviewed his bid.

"I think they're taking it very seriously from what it sounds like," Rasner said. "There's no holding back. The money isn't the issue right now, bringing all the pieces together is the issue."
