NY tends to keep everything under wraps, for good reason.
There is a civil suit running at the same time. trump is trying to claim that it's not legal, because he's compelled to testify in a civil case. He's claiming that testimony from that case will jeopardize his criminal cases. Said no innocent person ever.
There is no question that trumpco has been operating like a Mafia organization for decades. The moron went and got himself elected POTUS, and all of his ugly secrets have come to the fore.
In the case offered in this thread, trumpco is guilty of fraudulent activity re. the valuations of his properties. Inflating values for the purposes of obtaining loans, and deflating values for tax purposes.
They have the evidence. There is a bit of a disagreement right now over the probability of proving that trump KNEW about this fraud.
Does anyone believe that this went on behind his back?
If so, then they are the same people who believe that Gov. Christie knew nothing about the plot to shut down the GW Bridge.
