Who decides when a fact was omitted? Was the fact pertinent (note: there's a lot of wiggle room here)? How much investigation has to be done to uncover whether there was a lie by omission or actual ignorance?
What would the penalty be?
Thinking you can legislate your way out of this is hopeless idealism.
Demonstrating that a fact is omitted with dishonest intent is tricky business. That doesn't mean we can't guess, but the law does not go by guesses.
in any case, i've watched npr and nyt, two of my mostly former news sources, wrench from simply being biased to being outright hysterically partisan and dishonest. covid (over-)coverage being the most blatant, but it's been a long disintegration of truth and trust.
this is just a little part of the overall movement toward captured capital and centralized power, sweeping up news media along the way (note that these are editorial decisions, with editors seeking favor from the powerful). we're in for a rocky ride.

Picard: The first duty of every Starfleet officer is to the truth. Whether it's scientific truth, or historical truth, or personal truth. It is the guiding principle upon which Starfleet is based. If you can't find it within yourself to stand up and tell the truth about what happened you don't deserve to wear that uniform.
This is literally mental gymnastics, why would it clear their conscience if they intended to mislead? It only clears their conscience because they're doing mental gymnastics to convince themselves that they're not technically lying.
