Who is responsible for port security in the United States?

The agency responsible for port security in the United States is Customs and Border Protection (CBP). This agency plays a crucial role in ensuring the safety and security of ports by enforcing laws and regulations that prevent illegal activities, such as smuggling and trafficking, while also facilitating legitimate trade. CBP's responsibilities include monitoring the movement of goods and people across U.S. borders, which encompasses various checkpoints, including ports, airports, and land crossings.

CBP coordinates with other federal, state, and local authorities to assess potential threats and enhance security measures in port areas. They are also instrumental in implementing programs such as the Container Security Initiative (CSI) and the Customs-Trade Partnership Against Terrorism (C-TPAT), which aim to strengthen security both at ports of entry and beyond.

While other agencies listed have important roles in broader security and law enforcement, their focus does not specifically center on port security. The Department of Transportation primarily oversees transportation infrastructure rather than law enforcement. The FBI focuses on domestic security and federal investigations, while ICE deals more with immigration and customs enforcement issues rather than port-specific security measures. Therefore, CBP’s comprehensive role makes it the key agency responsible for port security in the U.S.
