What GAO Found

This statement today highlights the key findings of GAO's May 8, 2013, report on the TWIC program, which addressed the extent to which the results from the TWIC reader pilot were sufficiently complete, accurate, and reliable for informing Congress and the TWIC card reader rule.

Why GAO Did This Study

This testimony discusses GAO's recent work examining the Department of Homeland Security's (DHS) Transportation Worker Identification Credential (TWIC) program. Ports, waterways, and vessels handle billions of dollars in cargo annually, and an attack on our nation's maritime transportation system could have serious consequences. Maritime workers, including longshoremen, mechanics, truck drivers, and merchant mariners, access secure areas of the nation's estimated 16,400 maritime-related transportation facilities and vessels, such as cargo container and cruise ship terminals, each day while performing their jobs.
