How many groups doing deals with Russians and Ukrainians?

This is what the Mueller report should have shown, the complete sequence

Hillary using Steele to buy Russian dirt. Manafort using Ukraine to acquire dirt. Biden an Gore in Ukrainian gas board dirt. Trump doing hotel deals an digging up dirt. Uranium One, then add to this whole mess, the FBI conspiracy against Trump.

It is a zoo, quite frankly, and that is a good summary of the whole stinky Mueller mess, and the Mule Manure will forever be associated with the name Mueller.  A new form of MMT, Mule Manure Theory.

This time line is nuts:

Start here:

In 2013, Romanian hacker Marcel Lehel Lazăr (aka "Guccifer") distributed private memos from Sidney Blumenthal to Clinton on events in Libya.

According to security researchers at Secureworks the email leak was caused by Threat Group-4127 (TG-4127), 

All through the summer of 2015, the DOJ was releasing Hillary's personal stuff.

Then after the personal server fiasco we move on to DNC hacks: By the mid 2015,  the FBI already knew about the first DNC hack, and emails everywhere,
Sanders, Oct 2015:

 “The American people are sick and tired of hearing about your damn emails.”

Sanders Dec 2015:

Sanders apologizes to Clinton directly for staffers who accessed private voter data belonging to his rival’s campaign.

Emails, hacking and data theft all the rage for over a year. Now we get the Trump collusion:

Mar 31, 2016  Papa proposes a summit

Cyber attacks that successfully penetrated the DNC computing system began in 2015. Attacks by "Cozy Bear" began in the summer of 2015. Attacks by "Fancy Bear" began in April 2016. It was after the "Fancy Bear" group began their activities that the compromised system became apparent.

Apr 15 2016 Papa hears 'email', third hand
Apr Guccifer gets busted soon after installing a second virus.
May 2016 Downer meeting, fourth hand word of email

DOJ emails show Nellie Ohr on May 30, 2016, directly alerted her husband and two DOJ prosecutors specializing in international crimes to the discovery of the “black ledger” documents that led to Manafort’s prosecution.

June 9, Trump Tower meeting
Mid June Assange admits knowing of the emails.
Late June 2016, Guccifer 2.0 informed reporters to visit the DCLeaks 
June 2016, first DNC emails released

In May, Papa thinks this is typical political dirt, available for insider gossip. That leaves four weeks to negotiate and execute a collusion plot, two weeks if we count from the Trump Tower meeting. The obscure Russian lady reveals the emails about the same time Fancy bear is busted, game over.

July 2016:

FBI director James Comey recommends no criminal charges against Clintonfor her handling of classified information while she was secretary of state but rebukes her for being “extremely careless”. 

FBI director Comey  knew about the Crowd Strike report for nearly a year.

Then we are still doing personal server stuff:

2 September – FBI releases documents on Clinton emails
28 October – FBI reviews new emails related to Clinton server

Then we see it was a zoo of loose data, and the Russians would have known, right away, their stuff was going to be lost in the noise with a bunch of other stuff. It was an open market for dirty data. They rushed what they had, out the door; as did about four or five other groups more or less. All legal journalism , by the way.

Miftsad, Downer and Papa are just middlemen gossipers, introducing people.  Who sent the mysterious Russian lady? She arrived when the game was over, Guccifer busted, like one or the other parties attempting some last minute scam.
