Which department administers and oversees the TSA?

The Transportation Security Administration (TSA) operates under the Department of Homeland Security (DHS). This connection is significant because it positions the TSA within the broader context of national security and emergency management. The DHS was established in response to the events of September 11, 2001, with a primary focus on safeguarding the United States against threats to its internal security. The TSA plays a critical role in the nation's transportation security infrastructure, which includes overseeing airport security and ensuring safe travel for individuals. This makes the Department of Homeland Security the correct entity responsible for the administration and oversight of the TSA, emphasizing their commitment to protecting transportation systems from terrorist threats and ensuring the safety of passengers and cargo alike.
