Mueller didn't find any Russian connections. Now he want's to fish on some other waters.
He's barely gotten his file cabinets set up.
Mueller won't find anything that isn't there. However, considering Trump has been a high end real estate man all his life, working all over the globe, it isn't unrealistic to wonder if part of the reason Trump and his team SEEM biddable to Russian interests is some kind of financial blackmail on Russia's part.
Or maybe there isn't, which is what I'm hoping they find in the end. I hope Trump and his campaign are found totally innocent of any collusion or criminal activity, and this whole damned thing can end once and for all.
