So, Special Prosecutor Robert Mueller and New York Attorney General Eric Schneiderman have joined forces to tackle aspects of the Trump-Russia investigation.
People speculate that the purpose is to find state crimes to charge Paul Manafort with so that a presidential pardon won't protect him (presidential pardons apply only to federal crimes, not state crimes). If Mueller and Schneiderman find solid evidence that Manafort committed state crimes, maybe the prosecutors can get Manafort to make a deal and roll over on Trump or others.
Since so many people are speculating, I figured I'd join the party. Maybe it's bigger than just Manafort.
Maybe Mueller is looking for a way to protect the Trump-Russia investigation in case Trump fires Mueller or tries to otherwise impede the investigation. Trump indicated that he has considered firing Mueller.
Also, some Republican Congressmen want to pass a law limiting Mueller's investigation into Trump and Russia.
Maybe Muller is sharing evidence with Schneiderman in case Trump or Republicans manage to stop Mueller's investigation. If Mueller is shut down but Schneiderman has the benefit of the Mueller team's work, maybe Schneiderman can keep major aspects of the investigation alive.
I don't know, but it's worth a thought.
