Speaking philosophically rather than legally, should there be limitations on freedom of speech in the case of president-elects, or public officials in general, making unsubstantiated or even false claims? Saying, for instance, that millions of illegals voted. I think many people think that there's a public interest in false claims -- if made openly, they can be openly discredited. But in this particular case, while there is no evidence for the claim, there is also no evidence against it, so it can't, for the time being, be definitively refuted. Meanwhile, there are potentially big negative consequences -- eroding confidence in the electoral system, inflaming racial tensions, etc.
