US head of Afghan aid oversight resigns

The office that oversees billions in aid to Afghanistan will be without a chief for the second time this year, as its leader announced Thursday he was stepping down.
Herbert Richardson, acting special inspector general for Afghanistan reconstruction (SIGAR), said he will take a job in the private sector after he leaves his government post on September 2.
Created by Congress, SIGAR is tasked with investigating and leading audits of the more than $62 billion in aid distributed by the United States to Afghanistan since 2002.
