Former senator Russ Feingold (D-Wis.) is set to be named the State Department's special envoy to Central Africa.

Feingold lost reelection in 2010 to now-Sen. Ron Johnson (R) and since then has been running a liberal advocacy group called Progressives United. His move to the State Department was rumored last month.
