Was this still a meeting about adoption???????????
Of course not. Only a most gullible idiot would believe that.
The Russian government was letting the Trumps know they had dirt on Clinton. Junior and Manafort and Kushner went to the meeting with the Russian government cutout to arrange some terms about the release of that dirt.
In his emails, Junior told the Russians it would be better if the dirt was released in "late summer" because that timing would have the greatest impact on voter sentiment toward Clinton.
That is exactly when Wikileaks started releasing their dirt. Just as Junior requested.
The Magnitsky Act is a gigantic financial thorn in the side of Putin and the oligarchs. They want it repealed. The meeting with junior and Manafort and Kushner was obviously a quid pro quo meeting. Russia would release the dirt in late summer and Trump and the Republican Congress would repeal the Magnitsky Act. That was art of the deal.
Trump was totally in on it. Obviously.
