Weisselberg may be willing to spend the rest of his life in prison for Donnie, but I bet Ivanka is not. Unreported income and the employee+consultant scheme she did are some of Weisselberg's charges. If they indict him for those, there is no reason at all not to indict Ivanka. Then I think there is such a pattern of criminality and coverup, involving so many people, it is a perfect RICO prosecution.
A RICO prosecution tends to be very broad, charging everybody involved. That could include everybody who spoke on that platform on January 6th, Rudy, everybody who did criminal stuff during the Trump administration. AND confiscate all money that came from criminal activities, including all the money Trump paid his own businesses, money foreign governments paid in violation of emolument laws, money collected by fraudulent Trump grifts, etc. They could also charge members of congress who assisted insurrectionists.
