I've scrolled through the top ~10 or so comments, and none of them, describe or comment on the nature of the charges against Trump. To be fair to the commenters, most stories are vague. The charges relate to hush money payments to Stormy Daniels, but hush money is not a crime. It's also not a crime to have an affair with Stormy Daniels. So the most salacious parts of the story are not what the crime is. My understand…
My understanding from legal eagle on YouTube is that the payment was done illegally. Both in terms of taxes and in terms of how you are allowed to spend money on campaigning (she was hushed to aid the presidential campaign)
It seems more likely that this is pretty routine with Trump and had not much to do with the campaign. I doubt he started sleeping with hot women only after deciding to run for president; and there is probably a lot of money in it for the women. One of the perks of dating billionaires.
