Any fool with one eye and half sense could see that Mueller's goal was to get something on Trump.  He will eventually get someone to say what he tells them to say which will be grounds for charging Trump with some crime.  With 4500 federal laws on the books there is always something that can be construed as a crime if you put several $400/hr lawyers on it.  If the republicans are dumb enough to let it happen I guess that's were we are going.
