Lawfag here

Question – does the prosecutor have to present exculpatory evidence to a grand jury?

Short answer is yes and no

Some states require it

NY does not BUT it appears to be an ethical obligation when requested by the defendant and can be a basis to throw out the case later

Also if the grand jury actually requests such information it more or less must be presented

One would assume trumps lawyers would pursue this but I have seen his attorneys fail over and over – this lawfag would have done much better and for free

So called white hats s imply fail at lawfare its pathetic

Sauce
