costello was Cohen’s legal advisor and before that he worked for Giuliani
it appears Cohen is the rebuttal witness to Costello.
If an indictment hinges on these 2 witnesses, then, after all this time, they got nothin.
COSTELLO IS EXPECTED TO TESTIFY THIS AFTERNOON AND COHEN WILL BE THERE TO COUNTER HIS TESTIFY.
