“Hold on tight”
Indeed. Trump may be in the clear regarding Russia, as some pundits are saying, but Mueller has already veered from just investigating Russia collusion by charging Manafort for charges occurring way back in 2005. As said above on this thread, the Rats will keep looking and looking and looking and never stop.
I don't believe Manafort is facing a single charge dating back to 2005. The statute of limitations on such a charge would have expired years ago.
In Mueller's defense, keep in mind that Manafort had been under investigation by the FBI on many of these things as far back as 2012. Mueller charged him with these crimes even though they were unrelated to Mueller's mandate as a special prosecutor because the law requires any and all charges against a defendant to be adjudicated together.
