Who is the Secretary of Homeland Security?

The correct answer identifies the current Secretary of Homeland Security, who is an important figure responsible for safeguarding the nation against various threats, coordinating emergency responses, and overseeing the immigration system. Each individual mentioned in the options has either held significant political or military roles, but only one is officially in charge of the Department of Homeland Security as of now.

The Secretary plays a critical role in managing the country’s response to disasters, spearheading cybersecurity initiatives, and strengthening border security measures. This position requires a deep understanding of national security policies and the ability to navigate complex political landscapes.

The other options are not currently in that role, which helps clarify why they would not be the correct answer. Each has distinguished backgrounds that contribute to public service, but only the individual who holds the Secretary position directly oversees the Department of Homeland Security's mission and priorities.
