Anons, who is "EH"?
Eric Holder was my initial thought, also, but how does that resolve when LL is the key to connecting White House through to her predecessor?
How does S Powers and E Holder fit (at what appears to be the end of the string of individuals) make sense of this portion of Q1589?
It seems to be a circle rather than a linear progression from LL to the others. She sat at the inner circle,yes, but where was she when Eric Holder sat in that inner circle as AG? Or when S Powers was AMB? Perhaps it was before she was UN AMB?
