I see my post was unclear. Sorry about that. I was referring to Mueller's investigation getting too close to disclosing the depth of Russian Mafia and syndicated crime in Russia. Collusion between Putin's government and those syndicates. Basically the Trump/Mueller investigation is opening a Pandora's box of insight into the significant corruption in that part of the world. If Mueller get's too close the Russians will dump Trump to protect their secrets. IMO Thus the Russians , not Mueller, could end this presidency in rather spectacular fashion.
