Even if everything Bragg alleges is correct it is quite the stretch to say Trump was committing a felony by wanting to keep quiet payments to women who where going to brag about having sex with the guy. Heck Congress as a slush fund to pay out mistresses in the budget.
Trump was literally on his third marriage and this affairs allegedly took place a decade ago.
Trump is not charged for trying to keep women quiet.
But just the fact that he did it should be enough.
Boinking women involved in porn and paying them off to be quiet about it used to be frowned upon. This website started around the time an incident similar to that.
