The United States Secretary of Homeland Security is the main leader of a very important government department. This department is called the United States Department of Homeland Security. Its big job is to help keep people in the United States safe and secure. The Secretary is a key member of the Cabinet of the United States. This is a group of top advisors to the President.

This important position was created after the terrorist attacks of September 11, 2001. The goal was to better protect the country from future threats. The new department brought together many different agencies. These agencies were already working on homeland security in various ways.

Some of these groups include the Coast Guard. They protect our waters and coasts. U.S. Customs and Border Protection looks after our country's borders. The Transportation Security Administration (TSA) helps keep air travel safe. The Federal Emergency Management Agency (FEMA) helps people during natural disasters and emergencies.

Currently, Kristi Noem is the Secretary of Homeland Security. She started her role on January 25, 2025. On March 5, 2026, President Donald Trump nominated Senator Markwayne Mullin to take over this position. He is expected to begin serving on March 31, 2026.

Who Takes Over if the Secretary Can't Serve?

Sometimes, the Secretary of Homeland Security might not be able to do their job. In these cases, there's a special plan for who takes over. This plan is called the "order of succession." It makes sure that someone is always in charge of keeping the country safe.

The Homeland Security Act of 2002 sets out this order. It also allows the Secretary to create a specific list of who would take over. As of November 8, 2019, the main order of succession is:

  • Deputy Secretary of Homeland Security
  • Under Secretary for Management
  • Commissioner of the U.S. Customs and Border Protection
  • Under Secretary for Strategy, Policy, and Plans
  • Administrator and Assistant Secretary of the Transportation Security Administration
  • Administrator of the Federal Emergency Management Agency

There were some discussions about how this order was put in place. However, the main idea is to always have a clear line of leadership.
