President Barack Obama nominated John Carlin as the Justice Department’s chief national security lawyer.
Carlin has held the post of acting assistant attorney general for national security since March when Lisa Monaco left to become the president’s homeland security and counterterrorism adviser.
The nomination requires Senate approval.
A graduate of Harvard Law School, Carlin is a career prosecutor who previously worked as chief of staff and counsel to former FBI Director Robert Mueller.
He also previously prosecuted homicide, public corruption and other cases at the U.S. Attorney’s Office in the District of Columbia.
In recent years, Carlin coordinated a group of federal prosecutors trained to tackle computer hacking and intellectual property cases.
