If you haven't seen this, here's the link:
Anti-Trump Corker was the only Republican named in the article to have received this info.
“And now today, we find that Obama’s State Department sent classified info in emails to multiple Senators regarding Russiagate”
Despite all that you listed, I think we are still seeing the tip of the iceberg.
The Senators who received this information are now witnesses. While Senators cannot stop what people send to them, what they do as a result becomes important. I see Warner-VA is one of them. He is the clown who sits on one of the Senate investigating committees. He was found previously to have tried to come in contact with spy-dossier-Steele outside of the COmmittee. That alone should have removed him from the Committee and been forced to testify to the Committee about all of his knowledge and interactions on the issue. Of course the swamp circles the wagons to protect their own most of the time, but all the time when it is a democrap.
