I was initially assigned to the American Consulate in Aden, not as Principal Officer but as a supernumerary officer to handle Yemen affairs. We had no resident diplomatic mission in Yemen at the time. People from Aden went up to Yemen regularly.
It was the view of the people in the Department of State that the handling of Yemen affairs from Aden was too much of a burden on the then Consul, so an additional officer was named to the American Consulate at Aden to handle Yemeni affairs. I was designated for that task.
