This legislative proposal aims to extend the operational authorization of a key Department of Homeland Security component. Specifically, it addresses the Countering Weapons of Mass Destruction Office , which plays a crucial role in national security efforts by mitigating threats from such weapons. The bill amends the Homeland Security Act of 2002 to change the office's expiration date. Instead of expiring five years after the enactment of the Countering Weapons of Mass Destruction Act of 2018, its authorization will now extend until February 28, 2027 . This extension ensures the continuity of the office's vital functions in protecting the nation from weapons of mass destruction threats.
