What appears to be perfectly believable.

The existing president, Trump, does not believe he is innocent and can manage the Russian investigation by himself, as some writers of news suppose. He knows he is guilty!
It feels for sure, there was a person-  probably Flynn or Manafort-  who established a back channel for trump from Washington to Moscow. Or, more correctly stated, from Trump to Putin.  They went 'transparent' with the subtle guilt   (that didn't happen),  against Jared Kushner, to hide the facts; saying he TRIED to do it... but did not.
It is obvious that Trump is speaking regularly to Putin, and between them, they work out how much they will do to pretend to be against one another.  
There is NO DOUBT, Donald Trump is ENJOYING, even reveling in... being 'the most powerful man on the known planet'.  Putin allows him to THINK he is.  (chuckling).  To find so naive a "strutter", with some money and just enough education to make him dangerous-- is a THRILL AND A LAUGH to the Russians,  (and not to leave out most of us, who also see it as a pitiful laughing--tho serious matter.) 
It is no secret to any who know me, how I disrespect and disagree with the senators, house reps, and most people who call themselves 'republican',  in government..  Especially when they pretend their tightwad selfishness and sinful self love is 'Conservative-ism'.  Yet THIS particular congress, with it's speaker and majority leader-  being as crooked as they are, as snide as they are and how they enjoy both supporting trump's lies, but adding a few exaggerations and lies of their own-- this one takes the top UGLY AWARD!  Supporting the trumps, the rich, and themselves and thinking we are so stupid that when they stand up there with their mushmouth and say, "we are trying to work for the American people"  - that there is ANY one who actually listens, and if hearing, they want to throw up.
This group of repubs KNOW they should do any and all to get the trumps out of government. But they have no one else to get all the junk done they want to do. Pence???  Another laugh. they do not want the weak minded follower with no ideas and no spine, in their presiding seat.
Where will all this go?  Your guess is as good as mine.  I sincerely hope that Robert Mueller SOON and VERY SOON brings in his report, and there will be so much proof, that trump will resign on the promise that he wont have to do jail time.
Sessions quite possibly has been forgiven and drawn back in by his assurances that  "NO one will every know... "
