As far as I'm concerned, it all ties together. Kerry has been conducting a shadow State Department, meeting with foreign dignataries and conducting negotiations, just like he did in Paris with the NVA. The film of the KLA fund raiser is just tangible evidence of one instance. It is all the same, though.
I speculated about the shadow cabinet. The KLA is one aspect of it, on the fundraising side. If he has actually been meeting with or having Holbrooke or other minions meet with Iran, Syria, etc., that might be illegal.
But, the Democrats will point to it as proof that he is able to put together an international coalition.
