Who We Are

The Homeland Security Experts Group (HSEG) is an independent, nonpartisan group of homeland security policy and counter-terrorism experts who convene periodically to discuss issues in depth, share information and ideas with the Secretary of Homeland Security and other policymakers, increase awareness of the evolving risks facing our nation, and help make our country safer. The HSEG is co-chaired by former Secretary of Homeland Security Michael Chertoff and former Congresswoman Jane Harman. The HSEG, while independent in its operations and pursuits, is supported by The MITRE Corporation.
