Trump is probably on the list, so he has to protect that. The Democrats had it during their entire presidency; even if they didn’t want turmoil during their time in office, they could have released it after their presidential defeat and before Trump took office.
Even if it comes to light, I have doubts anything will come of it. Look what happened with the Panama papers. Basically only Iceland did anything about it.
Australia acted on it for what it’s worth.
they bombed a reporter over it.
Iceland had the highest profile result so perhaps it may seem that way, but many countries investigated and prosecuted individuals. In addition, it caused the entire global financial system to redouble AML efforts.
