“Matt Olsen is a consummate national security leader and professional whose long record of service to the nation will serve him well in his new role as the head of the Justice Department’s National Security Division,” said Jamil N. Jaffer, Founder & Executive Director of the National Security Institute at the Antonin Scalia Law School at George Mason University.  “While we are sad to lose Matt as a member of our Advisory Board, a capacity he has served in since NSI’s founding, we are thrilled that he will once again be in position help protect our national security,” said Jaffer, who served alongside Mr. Olsen in the Bush Justice Department.  “We need more people like Matt Olsen in the government at a time of great threat to our nation and we are excited to work with him in his new role,” said Jaffer.
