The Obama administration’s special envoy to Sudan is calling for a major shift in US policy toward the Sudanese government. On Thursday, Ambassador Scott Gration said the US should remove Sudan from a list of states sponsoring terrorism and unwind sanctions imposed since 1993. Speaking before the Senate Foreign Relations Committee, Gration said the sanctions are preventing the delivery of basic humanitarian aid and development of basic infrastructure in Sudan’s most desperate regions. He added that maintaining the sanctions would be a “political decision” that is “backed by no evidence.”
