I’m not an attorney, much less a Constitutional one, so I can’t answer that.
As a rational man (I don’t care what they say, LoL), it stands to reason you shouldn’t be able to publish/air/post false information about someone, particularly in a time when the public is trying to make up their mind if they are worthy of their vote or not.
This isn’t just a loss for the candidate, but a loss for those who might have supported him, and for the nation as a whole. So it is a big deal when the media lies.
It might be time to take the punks to task for their subversion.
