The man who has led the US nuclear security agency since 2007 is stepping down next month after presiding over a 20 percent increase in the agency's budget but also some management missteps that have raised questions about the agency's ability to carry out its mission.
Tom D'Agostino announced Friday he is leaving the National Nuclear Security Administration, which funds and oversees work at the Sandia and Los Alamos national labs in New Mexico. The research centers employ about 20,000 people in the state. He was appointed to the post by President George W. Bush.
Mr. D'Agostino issued a statement saying he wants to spend more time with family and says periodic leadership changes make organizations healthier, the Albuquerque Journal reported.
