I believe reasonable people have said over and over, there might be nothing improper about talking with russians, what is problematic/questionable is the lying (conveniently forgetting) that one talked to russians.  And, as important, why are so many of 45's associates talking with russians and then lying about it, whether the lies are explicit or forgetting to include them on national security clearance forms.  Is this a matter of everyone now knows they messed with their electoral process and we'd better not admit we were hanging out with them because we'll be suspected of colluding or is it that they colluded, or something else.
