Transportation Security Administration

The Transportation Security Administration (TSA) is an agency of the United States Department of Homeland Security, established in response to the September 11 attacks. Its core mission is to "Protect the nation's transportation systems to ensure freedom of movement for people and commerce." The agency's headquarters are located in Springfield, Virginia.

The TSA's primary responsibilities include screening passengers and baggage at over 450 U.S. airports, employing Transportation Security Officers (TSOs), Federal Air Marshals, explosives detection dog handlers, and bomb technicians. Beyond aviation, the TSA also develops policies and oversees security for other transportation modes, such as highways, railroads, bus networks, mass transit systems, ports, pipelines, and intermodal freight facilities. Key programs offered to the public include TSA PreCheck® for expedited screening and the Federal Air Marshal Service.

As of June 2026, Ha Nguyen McNeill serves as the Senior Official Performing the Duties of the Administrator. The agency is actively preparing for anticipated record-breaking travel periods, such as the Fourth of July holiday, and is implementing new technologies to enhance efficiency and security. Recent initiatives include expanding touchless ID screening options, such as a new partnership with Google Wallet for TSA PreCheck travelers, to streamline the security process at airports nationwide. The TSA continues to focus on an intelligence-driven, risk-based approach to security, integrating advanced technology and a professional workforce to counter dynamic threats.
