Which individual leads the Department of Homeland Security?

The individual who leads the Department of Homeland Security is the Honorable Alejandro Mayorkas. This position entails overseeing a comprehensive array of responsibilities related to national security, immigration policies, cybersecurity, emergency management, and disaster response. Mayorkas was confirmed as the Secretary of Homeland Security in February 2021, making him the first Latino and immigrant to hold this role, which underscores the importance of diversity and representation in leadership positions within the federal government.

The other options represent individuals who do not hold this position. Kristie Noem is the governor of South Dakota, Donald Trump is a former president, and James David Vance is known for his political and writing career, but none of these individuals are currently responsible for leading the Department of Homeland Security.
