Mueller’s team just dropped, literally minutes ago, its superseding indictment on Manafort and Gates. You can just look at the cover page to see who is indicted for what. 32 counts, mostly dealing with financial transactions and bank fraud and tax fraud (money laundering, basically) all before Manafort was Trump campaign manager.
I did a search for “Trump” — his name does not appear in the document.
But it seems that Manafort and Gates are caught by the short hairs. They have to cut a deal.
