Precisely. But as it stands, they even haven't made a case against Tiktok, let alone private investments by Chinese companies.
There's nothing stopping the DOJ from laying charges against Tiktok US (the corporation) if there's evidence of contravening US law. But there is plenty of political hay to be made by suspecting that there might be. What laws, you ask? That too hasn't been clear, which helps explain why these bills fail again and again.
I mean, yeah maybe. If there's a real national security risk it would make sense. Not that I think either of those companies are in any way trustworthy, but let's not compound the dangers to the public with CCP interference.
