The office in charge of overseeing billions of dollars being spent to rebuild Afghanistan is undergoing a shake-up for the second time this year.
Herbert Richardson, the acting special inspector general for Afghanistan reconstruction, announced Thursday that he is leaving to take a job in the private sector.
Richardson became head of the office, known as SIGAR, after Arnold Fields resigned under fire in January for alleged mismanagement.
"After more than 37 years of public service, I've decided to accept an opportunity in the private sector, at a time when I'm convinced SIGAR has changed course, is producing results, and is being led effectively by the new leadership team that I've put in place," Richardson said in a statement.
He was an FBI agent and a manager for 20 years and deputy inspector general at the Energy Department for 16 years.
Richardson leaves next month and his deputy, Steve Trent, will step in until a permanent replacement is named.
The $70 billion U.S. rebuilding effort in Afghanistan is part of an international program to improve security, development and government in the war-torn nation.
