Which agency is responsible for conducting the background checks for O'Hare Badges?

The Transportation Security Administration (TSA) is the agency responsible for conducting background checks for O'Hare Badges. The TSA oversees the security for transportation systems in the United States, including airports, and ensures that all personnel who will have access to secure areas meet specific security requirements. This is critical for maintaining safety protocols in airports, making the TSA's role essential in vetting individuals who require access to sensitive areas.

While other agencies have significant roles in transportation safety and security, they do not directly manage the background check processes for airport badges. The FAA focuses more on civil aviation standards and regulations, the NTSB investigates transportation accidents, and the DHS encompasses a broader range of security-related responsibilities. However, it is the TSA that explicitly handles the background processes related to airport access and employee credentials.
