Countering Weapons of Mass Destruction Extension Act of 2023

This bill extends the authorization period for the Department of Homeland Security's Countering Weapons of Mass Destruction Office from 5 to 7 years. It does not change the office's core mission but adds two new requirements: (1) a 180-day report on employee engagement plans, and (2) a one-year review by the Comptroller General on the office's program prioritization and coordination. The extension specifically excludes sections related to the Chief Medical Officer and medical countermeasures programs (sections 1931-1932). The bill primarily affects the DHS office's operational timeline and internal accountability, with no new policy changes for external stakeholders.
