What is the role of the Secretary of Homeland Security?

The role of the Secretary of Homeland Security is fundamentally focused on overseeing domestic security. This position is critical in coordinating and managing efforts to protect the homeland from various threats, including terrorism, cybersecurity risks, natural disasters, and other emergencies affecting the United States. The Secretary is responsible for implementing policies and programs that enhance the safety and resilience of the nation, ensuring that various federal, state, and local agencies work together efficiently to respond to and mitigate risks.

Managing the Department of Defense, conducting foreign diplomacy, and administering veterans' affairs fall outside the scope of the Secretary of Homeland Security's responsibilities. Each of those areas is overseen by different governmental officials or departments that have distinct mandates related to national defense, international relations, and veteran services, respectively. Thus, the focus on domestic security distinctly characterizes the role of the Secretary of Homeland Security.
