In a recent government meeting, expert witnesses provided critical insights into the implications of illegal immigration on national security. Dr. Kelly Brown, a retired U.S. Army combat veteran and former military adviser at the Department of Homeland Security (DHS), emphasized the significant changes in border security strategies since January 2021. She described her transition from a military adviser to a border crisis specialist during her tenure at DHS, where she played a pivotal role in implementing a comprehensive border security system that included physical barriers, military support, and coordinated federal and state efforts.

Dr. Brown highlighted that the border security measures established during her service were dismantled in early 2021, leading to a shift in focus from preventing illegal entry to processing illegal immigrants. She noted that the cessation of wall construction and the reduction of military support contributed to increased challenges in managing illegal immigration.

The meeting also featured Timothy Healy, the director of National Security for Buchanan and Edwards, who previously led the FBI's terrorist screening center. Healy's experience underscores the importance of information sharing and coordination in safeguarding national security while balancing civil liberties.

Additionally, Alex Norasta, vice president for economic and social policy at the Cato Institute, contributed to the discussion with his extensive background in economic research and policy analysis.

The testimonies from these witnesses shed light on the evolving landscape of U.S. border security and the pressing need for effective strategies to address the complexities of illegal immigration and its ramifications for national security. The committee is expected to delve deeper into these issues during the upcoming question and answer session.
