I agree with your point: Trump was not convicted for sexual assault.
However, the Russian stuff....Trump and his cronies obstructed that investigation so much that we really don't know. He refused to be interviewed by Mueller's team, he claimed executive privilege for anything related to this investigation, and had his people refuse to cooperate. While he might legit be not guilty of that, his actions were not those of an innocent man with nothing to hide. Compare and contrast how Biden acted for the classified documents he mistakenly took as VP. He sat for hours with the special prosecutor -- because he had nothing to hide....
As for Hunter's laptop: A few things.
First, the NY Post ran the story...but only after several other right-wing publications passed on it. In fact, the actual writer refused the byline. Why? Well, even they were skeptical about what this information was and how it was obtained. The whole story around it was, to say the least, suspicious. Deny that all you want, but if it was a legit story, why didn't the Wall Street Journal (which was originally give the info) refuse to break it?
Second, even at this writing, a lot of the info on the laptop has not been proven true. Sure, some has. But we don't know if everything was legit or was planted. Is it outside the realm of possibilities that Russia has some involvement? We know they helped Trump in 2016.
Finally, for Fox, they have the most viewers of any of the news channels. So, that is very influential. It isn't propaganda to focus and report on what they are or are not doing. I mean, the argument could be made that they are more moderate than NewsMax or OAN, but not by that much. And, remember, they paid around three-quarters of a billion dollars to settle with Dominion, because they knowingly lied about the company. That is a massive amount of money. If they went to trial and lost....it would have likely been even larger.
