I'm honestly lost on what you might be alluding to with the "campaign finance violations"; but that is a classic up there with the remarkable rate that whistle-blowers turn out to be guilty of sexual assault nothing-burgers. I expect candidates will routinely violate campaign finance laws and don't see why that is more than a minor problem until someone outlines what the actual issue is in a specific case.

If they're taking millions of dollars from Chinese NGOs that would be a problem. If they filled out a form wrongly and there is no motive involved that isn't interesting. Might be worth a few political points on a slow news day.

Those laws are a poster child for the high risk of selective enforcement leading to political corruption.
