I suspect Trump will fake a heart attack and resign. He's said that the job isn't as "fun" as he thought it would be. Republicans are getting desperate to get rid of Mueller...attacking him personally, and then attacking Sessions so they can replace him with somebody who will fire Mueller or shut down the investigation.

Trump is deeply, deeply involved in Russian financial snares. Wilbur Ross, on the board of the Bank of Cyprus, and Trump's pick for Secretary of Commerce, might know all the details of a lot of dirty money transfers. The Bank of Cyprus was the bank of choice for the Russian mob and Russian intelligence services. Ross is probably on Mueller's radar. Then the sh*t will really hit the fan.
