Much as I'd like to F! DeNiro, this is a very old story that hasn't gone anywhere.
There was a report on Free Republic from 2016 where the US government was able to confiscate $30 million from De Nero for engaging in illegal offshore activities (Barbuda ?). He forfeited the money when he failed to appear in court. This is why he hates Trump. If he had contested the seizure, it would have proved his involvement.
Sshhhh! This is a BOMBSHELL... breaking news! Obviously not a blog pimp appealing to pizzagate believers for click revenue...
