Innocent in till proven guilty. At this point in time all that can be verified is Kerry met with people. That you think he did something has no legal bearing.
1) That he spoke with members of Congress would be lobbying, legal.
2) That he spoke with the French and Germans, maybe legal, maybe not, we do not know at this time.
3) That he spoke with the Iranians, maybe legal, maybe not, we do not know at this time.
4) Is he being investigated at this time, maybe, maybe not, we do not know at this time.
5) In due time answers may come out.
6) If he is dirty hopefully he gets what he deserves.
