The National Security Division is the first-of-its-kind in the nation for a United States Attorney’s Office and is responsible for combatting national security and cyber security threats facing our region and our nation. Protecting national security is the highest priority of the Department of Justice and the United States Attorney’s Office.
The National Security Division consists of the Terrorism and Export Crimes Section and the Cyber and Intellectual Property Crimes Section. Due to the complexity of the cases handled by these Sections, the close coordination needed with other districts and DOJ by these sections, the increased reliance on classified information in their prosecutions, and the overriding goal of prevention shared by these sections, they joined together to form the National Security Division.
Additional information about the Terrorism and Export Crimes Section and the Cyber and Intellectual Property Crimes Section, which are the two Sections within the National Security Division, may be found by clicking on the following tabs:
Patrick Fitzgerald graduated from Harvard College and the UCLA School of Law. He clerked for the Honorable Pamela Ann Rymer and then was a civil-litigation associate at Munger, Tolles, and Olson. He joined the USAO in May 1994. After serving in the Training Section (later called General Crimes), he joined the OCDETF Section in 1995. In the OCDETF Section, he became coordinator for the USAO’s methamphetamine and precursor-chemical prosecutions. He investigated, tried, and wrote appeal briefs in many narcotics cases. These included the trial of the then-largest PCP lab in the district’s history, the first use of a wiretap on a chemical supply company in the nation, and the drafting of the 353-page government brief in the appeal from the first Mexican Mafia trial (“EME I”). In non-drug investigations, he tried the first counterfeiting case in the district (and one of the first in the nation) in which the defendant used a computer to create the counterfeit image and co-tried the former CEO of a movie studio on tax-evasion charges. From 2001 to 2004, he was Deputy Chief and Chief of the General Crimes Section. In late 2004, he stepped down from being a supervisor and became a line AUSA in the Public Corruption and Government Frauds Section. In late 2005, he began to work on terrorism investigations. He became a Senior Litigation Counsel in 2006 and was one of the founding members of the National Security Section in 2007. He was Chief of the National Security Section from late 2009 to August 2015. From August 2015 to September 2016, he served as the First Assistant United States Attorney. Outside the USAO, he went on a detail in 2009 to serve on the President’s Guantanamo Review Task Force. He also has taught Evidence at the University of Southern California Gould School of Law. He received an EOUSA Director’s Award in 1999 and a Director of National Intelligence Award in 2012.
Chris Grigg is the Chief of the Terrorism and Export Crimes Section (TEC), within the National Security Division. Mr. Grigg graduated summa cum laude with a bachelor’s degree in history from UCLA and earned his law degree from the University of Southern California Gould School of Law in 1997. While his classmates were preparing for the bar, Chris joined the military, where he was the distinguished honor graduate for his class at the United States Army’s Ranger School and served as a team leader in the Army’s 75th Ranger Regiment. Chris then returned to civilian life and began his legal career in civil litigation before joining the Los Angeles County District Attorney’s Office as a Deputy District Attorney. He joined our Office in November 2007 and joined the National Security Section (the predecessor to the TEC Section) in May 2008.
Since joining the National Security team, Chris has worked on some of the Office’s biggest National Security cases, including the “MEK” case in Santa Ana, the investigation and resulting prosecutions arising out of the 2008 Mumbai terrorist attack, and the trial and appeal in the seminal International Emergency Economic Powers Act case United States v. Guo. More recently, Chris was a member of the trial team that secured convictions and 25-year sentences for the lead defendants in United States v. Kabir, et al., in Riverside, the first material support trial in the District’s history.
From 2010 to 2015, AUSA Grigg served as a co-coordinator of the Office’s Export and Anti-proliferation Global Law Enforcement (“EAGLE”) Task Force. He was Deputy Chief in NSS between 2013 and 2015. He received a Director of National Intelligence Award in 2009. In 2015, Chris was awarded the Helene and Joseph Sherwood Prize by the Anti-Defamation League for his work on the Kabir case.
