Two more senior State Department officials are preparing to leave the already hollowed-out top ranks at Foggy Bottom.

Robert Hormats, undersecretary for economic growth, energy and the environment, is said to be moving on around mid-June after four years on the job.

Hormats has held numerous senior economic and trade positions, starting with the Nixon National Security Council. He was also deputy U.S. Trade Rep in the Carter administration and an assistant secretary of State in the Reagan administration before joining Goldman Sachs as vice chairman (international).

We hear he’s taking some time off before deciding what to do next, either here or in New York.

Undersecretary for public diplomacy and public affairs Tara Sonenshine is leaving in July after 15 months in the job, likely headed to an academic or media gig.The Emmy Award-winning former editorial producer of ABC News’ Nightline also worked on the Clinton National Security Council and was more recently executive vice president at the U.S. Institute of Peace.
