Good read. Kislyak certainly played a major role in SpyGate...especially regarding Sessions & Flynn, but he also meet with Kushner & Carter Page as well. And in the background, he also met with both Butina & Obama numerous times, as well as multiple times with Obama's confident & Ambassador to Russia, McFaul.
Kislyak began openly courting the Trump Campaign in April 2016. Something to consider: Brennan made a secret trip to Moscow in March 2016. Just a coincidence? Remember, Brennan was the key-master of SpyGate.
