News outlets in the United States are reporting that Christopher Hill, the lead American negotiator on North Korea, is expected to be nominated as the next U.S. ambassador to Iraq.

There has been no official confirmation of the reports Monday on CBS, ABC, the Associated Press and Reuters, which quote unnamed officials who say Hill is expected to be the nominee.

Hill is currently the Assistant Secretary of State for East Asian and Pacific Affairs.

Hill has previously served as ambassador to South Korea, Poland and Macedonia. He was also special envoy to Kosovo. Before he started his career in the foreign service, Hill served as a Peace Corps volunteer in Cameroon.

If nominated and confirmed by the U.S. Senate, Hill would replace another career diplomat, Ryan Crocker, as Washington's top diplomat in Iraq.
