ALBUQUERQUE, N.M. – The man who has led the nation's nuclear security agency since 2007 says he's stepping down next month.
Tom D'Agostino announced Friday he's 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.
The Albuquerque Journal reports (http://bit.ly/101XRFw ) D'Agostino has presided 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 national security mission.
D'Agostino says he wants to spend more time with family and says periodic leadership changes make organizations healthier.
His announcement came on the same day the agency ordered security stepped-up at the Los Alamos National Laboratory.
Lab spokesman Kevin Roark declined to say why security was increased but noted the order was exclusive to the Los Alamos facility.
