WASHINGTON, Sept. 27 (UPI) -- One of the United States' top national security officials has decided to step down from his post next month and go into the private sector, the Justice Department said Tuesday.
John P. Carlin, the head of the department's National Security Division, will resign effective Oct. 16.
Carlin, 43, oversaw numerous prosecutions involving matters of national security, including that of 2013 Boston Marathon bomber Dzhokhar Tsarnaev. He also presided over espionage charges against Chinese military hackers.
"For the better part of two decades at the Department of Justice, John distinguished himself as a leader who skillfully used all the tools at his disposal to enhance our public safety and uphold our national security," U.S. Attorney General Loretta E. Lynch said in a statement Tuesday.
Carlin, who was appointed assistant attorney general for national security by President Barack Obama's administration, will go to work in the private sector as the president's second term nears a close.
Carlin started his term as NSD chief in 2009 and is the youngest and longest-serving person in that position. He was formerly chief of staff and senior counsel to former FBI director Robert S. Mueller.
