The Trumpanzees are not going to be happy, but Weisselberg may have already flipped.
Weisselberg as CFO/FD of the Trump organization could have enough information to put Trump away for good.
Trump is not giving the current US government any choice. It is not clear why he is acting like this, but perhaps he realizes that it is only a matter of time before all of his fraud is uncovered. It is all or nothing for Trump, because time is his enemy.
He could end up as the modern-day Al Capone, where everyone flips once he is behind bars.
