US State Department is planning to appoint Tom Perriello as a new special envoy to Sudan. The move comes months after Democratic and Republican lawmakers called for the appointment of a top problem-solver to help prevent one of Africa's largest countries from sliding deeper into civil war, ethnic cleansing, and one of the world's worst humanitarian crises.

This also coincided with the decision of the US Ambassador to Sudan, John Godfrey, in his capacity as the unofficial envoy, to step down from his position.
