I honestly do not understand why a meeting between Trump and Putin could be a crime. To the date, no one has even ventured into this subject, concentrating instead on "evil Putin" and his plans to "destroy America". O'kay, perhaps, Putin would be happy to destroy America, but there is nothing unusual or/and criminal in setting up meetings between political leaders. Am I missing something important?
There is one other related thought. If we assume that a so called "Russian interference in the US elections" was criminal, then the US interference in the Ukrainian maidan and a de facto coup d'etat that followed was also criminal ... just remember Mrs.Nuland's admission that the US transferred 5 BILLIONS dollars (on the stretch of 10 years) to different NGOs in Ukraine which had been involved in preparation of that Maidan. 
So, if that was not criminal interference into internal affairs of another state, then what was that???
Ah, double-standards again... then do not blame Russia, period!
