Flying to Russia for an awards dinner ( RT) is enough to start an investigation? the FBI isn't Stasi .I don't disagree at all with the fact that the Trump campaign's characters were under surveillance; they were properly so. Your (group your) outrage about it, though, is hysterically funny. If Obama or Clinton's workers had been flying to Russia, having secret and not-so-secret meetings with Russians (or any other foreign nationals), and chatting via insecure phones with Russians, you guys would be calling them traitors and setting up the gallows for some hangings. But since the Russians connived and Trump got selected, you're now all butthurt that this is being revealed.
You (group you) are traitors to the United States.
and these were extraordinary steps -FISA warrants/informant(s) eavesdropping / digital investigations.
There was no underlying evidence of a crime - just like Mueller it was a fishing expedition.
No. Last time I looked- talking to Russians isn't a basis at all for an intrusive investigation
