Is this a scenario you came up with or this is another claim about Trump that's going around again?
It's circumstantial, but it's been going around.
Putin has a history of backing (financially and otherwise) hard-Right candidates in Europe who want out of NATO. Trump himself
was a hard right candidate who wants out of NATO.
Donald Trump is in debt, but has been blackballed by western banks -- Funny thing; brag about bankruptcy as a shrewd business move, and they won't give you a dime.
Putin owns the largest oil company in Russia, and was in the process of a $500
billion deal with Exxon, which Obama put the brakes on via sanctions... after which, the DNC hacking began, which 17 separate US agencies say Russia had a hand in, but Trump refuses to believe.
James Comey, as director of the FBI, brought the information to Senate Majority leader McConnell, who ordered him to keep it quiet. So instead, Comey announced, days before the election, new investigations... into Clinton.
Mitch McConnell's wife is now Trump's Secretary of Transportation. Rex Tillerson, Exxon CEO, is now Trump's Secretary of State.
These
could all be coincidences... Trump releasing his tax returns would prove it. Of course, Trump claims that his tax returns are far too complex to be properly understood... he needn't worry. There are forensic accountants who are skilled at unraveling even the most complicated of tax filings.
But of course, none of this is forthcoming... just one coincidence piled up on another.
