Seems to me this whole thing is intended to keep everyone occupied with a ridiculous salacious story that addresses zero of the problems facing us, meanwhile Uranium One and all the tendrils of real criminal activity get forgotten. Oh, and Stormy is cooperating because she is getting a bank account full of $$$$$.
I thought she was doing all of this to try to prolong her career. Floozies tend to become unmarketable when they age. Thus, Stormy found a way to get attention even after her sell-by date has expired.
I suppose we can all have different theories. Who knows for sure what motivates her?
