The involvement of the Russians and FBI Director Comey in the presidential election is extremely suspicious and suggest collusion by either one or both with the Donald Trump campaign. It's too big of a coincidence to ignore the fact that their involvement in this campaign greatly helped Trump win the election.
This should be investigated immediately and if true is a disqualifier and would give the Electoral College grounds for not proclaiming Trump president. You would hate to find out years from now that there was collusion and that something could have and should have been done.
