Is it possible Fitz won't bring the indictment yet to keep certain evidence out of Blago's hands now

If there is no indictment, Fitz doesn't have to turn over any of the tapes, list of informants, witness, etc, to Blagabitch yet. Maybe Fitz doesn't want to turn over any of that evidence just yet. By prolonging it, he can stretch it out and provide some cover for some of his witnesses. He wouldn't have to turn over the taped conversations to Blago either just yet. What does Fitz think Blago would do with the tapes, witnesses?

Perhaps Fitz is waiting for Blago to be impeached, so that he is even more isolated and marginalized, and most importantly, without the power to actually do much.

I wonder if the governor's office tapes its own phone calls. I wonder if they would be accessible under any Sunshine laws?
