What is the primary mission of the TSA?

The primary mission of the Transportation Security Administration (TSA) is to ensure the security of the traveling public in the United States. This includes safeguarding passengers and their belongings during air travel, as well as protecting transportation infrastructure from potential threats. The TSA implements various security measures and protocols at airports, such as screening passengers and luggage, and maintains a constant focus on identifying and mitigating security risks to enhance the safety of air travel.

Other options, while relevant to different aspects of the aviation industry, do not capture the core responsibility of the TSA. Ensuring fair competition in the aviation industry relates more to regulatory bodies like the Department of Transportation. Regulating air traffic control systems focuses on the operational side of air travel rather than security. Promoting international aviation agreements involves diplomatic and regulatory tasks that are distinct from the TSA's security mission.
