Otherwise it's just a private citizen meeting with foreign diplomats, which happens all the time and there's nothing nefarious about that.

Maybe it's all politicking, but then if it's good for the goose it's good for the gander.
If Pompeo had evidence of Kerry having illegal talks, he had the opportunity to provide this evidence to the FBI, seeing as he was part of the administration at the time. Instead he chose to 'slam' Kerry during a news conference.
But still no answer to the question if Kerry pretended to represent the US government, which would have been illegal.
That's the equivalent of an ad-hominen attack.
Anyone still trying to stir up this nonsense partisan battle is just distracting from the recent major world events.
Being lost in the moment of a blizzard of “crises” that really aren’t is intellectually paralyzing. Probably intentionally so.
