PSA: Trump's NY trial before Judge Merchan is about election interference, not "hush money" - please remember that's what it is.
Paying someone hush money to keep quiet about something that's arguably immoral, or at least, ethically sketchy, isn't illegal. Cooking the books to disguise such payments, although illegal, is merely a misdemeanor. Trying to affect the outcome of an election by cooking the books is a felony offense, which is what he's on trial for.
