What I have on POTUS being On The Job for a lot longer than any of us have expected.
Attached is a document I'm trying to find more to. This was from April '81.
Relating Muller to this case, the following is extracted from Wiki:
"he [Mueller]moved to Boston to work in the office of the U.S. Attorney's Office for the District of Massachusetts as an Assistant United States Attorney,[7] where he investigated and prosecuted major financial fraud, terrorism and public corruption cases, as well as narcotics conspiracies and international money launderers.[29]"
In other words, he was on the back end and Trump was on the front end of Russian money being laundered through the casino.
