U.S. Rep. Jackson Lee, D-Texas, introduced the Essential Transportation Worker Identification Credential Assessment Act (H.R. 3202) in late September.
The act requires the Department of Homeland Security to conduct a comprehensive security assessment of the transportation security card program. If signed into law it would require an independent analysis of the effectiveness of the TWIC program at enhancing security or reducing security risks at regulated facilities and vessels.
