Not simply a Kerry supporter - an active paid senior advisor.
I have to go now, but I think you should ping some interested parties back to this thread.
Sounds like Burns has moved around a bit more than most career State department types though.
Way back when (1992?) I remember sitting in a Chinese restaurant out in Tysons Corners and in comes Warren Christopher and one of "Jugears" Perot's top advisors, and they sat down to dinner together. A very large white woman I didn't immediately recognize sat down with them. I believe she must have been Madelein Albright carrying some spare pounds at the time.
So, you might ask, what's Perot's guy got to do with this? And, you would be right to ask that.
