There already exists a law: if there's a threat to national security (which there is), the executive branch has relatively broad discretion. You can't really "make a law" in the time remaining until election, not with Pelosi turning everything into a political showdown, and _especially_ not if China prefers Biden (which, according to Nancy Pelosi it does: https://www.youtube.com/watch?v=arS5qzS95cE).
Here's one way you could interfere with US elections without showing political ads BTW: show "vote" reminders only to people who you infer from data to be democrats. At a first approximation, to people in urban centers in swing states. Not an "ad" per se, but you can still swing the election quite easily - in swing states elections are close by definition. As far as I'm aware there exists no law prohibiting such interference.
This is how FB and Twitter are going to do it if the DNC doesn't like the final polls.
Then this trail would hopefully surface the evidence about this National Security issue and we are not left without a retraction like in the case where China was accused of planting chips in PC motherboards.
