Transportation Security Administration

The Transportation Security Administration (TSA) is an agency of the United States Department of Homeland Security (DHS) that has authority over the security of transportation systems within and connecting to the United States. It was created as a response to the September 11 attacks to improve airport security procedures and consolidate air travel security under a combined federal law enforcement and regulatory agency. The TSA develops key policies to protect the U.S. transportation system, including highways, railroads, bus networks, mass transit systems, ports, pipelines, and intermodal freight facilities. It fulfills this mission in conjunction with other federal, state, local and foreign government partners. However, the TSA's primary mission is airport security and the prevention of aircraft hijacking. It is responsible for screening passengers and baggage at more than 450 U.S. airports, employing screening officers, explosives detection dog handlers, and bomb technicians in airports, and armed Federal Air Marshals and Federal Flight Deck Officers on aircraft. At first a part of the Department of Transportation, the TSA became part of DHS in March 2003 and is headquartered in Springfield, Virginia. As of the fiscal year 2023, the TSA operated on a budget of approximately $9.70 billion and employed over 47,000 Transportation Security Officers, Transportation Security Specialists, Federal Air Marshals, and other security personnel. The TSA has screening processes and regulations related to passengers and checked and carry-on luggage, including identification verification, pat-downs, full-body scanners, and explosives screening. Since its inception, the agency has been subject to criticism and controversy regarding the effectiveness of various procedures, as well as incidents of baggage theft, data security, and allegations of prejudicial treatment towards certain ethnic groups.
