Edward O’Callaghan, principal deputy assistant attorney general of the Justice Department‘s national security division, has been named acting principal associate deputy attorney general at DOJ.
He will succeed Robert Hur, who will transition to a new role as U.S. attorney for Maryland, the department said Tuesday.
In his previous role, O’Callaghan helped DOJ’s assistant attorney general manage NSD units and components that include the counterterrorism and counterintelligence and export control sections.
Before returning to the department in 2017, he worked at an international law firm as a partner focused on securities and bank fraud, money laundering and corruption cases.
He previously was a Southern District of New York assistant attorney from 1999 to 2008 and co-chief of the district’s terrorism and national security unit from 2005 to 2008.
