Via the Miami Herald:  Top US Latin America Diplomat to leave post

In an email to staff members late Thursday, Arturo Valenzuela, the United States Assistant Secretary of State for Western Hemisphere Affairs, said he would be returning to his duties as professor of government at Georgetown University.

“As you may know the University gave me a two year leave of absence to serve in the Administration —and those two years have come to an end this spring,” he wrote in an email to staff, which was forwarded to The Miami Herald. “Although the exact date of my departure has not been set, it will take place sometime later this summer.”

I suspect that the experience has been rewarded (and frustrating), but I also suspect that life is a bit more enjoyable at Georgetown than it is at State.
