Part one of the After September series features Janice Kephart, a key author of the 9/11 Commission report, who explains how the September 11 attacks reshaped travel policy over the last 25 years — from passport rules and Real ID to the rise of biometrics and identity verification at the border.

The episode looks at successes and remaining gaps: how biometrics have improved air travel safety, challenges like biometric exit and privacy oversight, and why identity remains central to national security and the evolving threats to travel.
