Mueller is now on borrowed time. If he has any evidence that Trump was somehow colluding with the Russians in 2016, he has to produce it now.
Now that Trump has locked up GOP support in the Senate and there is no possibility of a law to protect the investigation, he will act quickly, certainly before the end of the year to shut down the investigation.
The Democrats will have a meltdown, but if there is no actual evidence, it will blow over in a few weeks.
The only real jeopardy to Trump would be if Mueller actually has any evidence of criminal acts by Trump, not dubious "obstruction of justice" charges.
