President Donald Trump has announced that he has fired Secretary of Homeland Security Kristi Noem and will appoint U.S. Senator Markwayne Mullin of Oklahoma as the new head of the Department of Homeland Security.

In a social media post, President Trump said that Noem will instead transition to a new role as Special Envoy for The Shield of the Americas.

Noem was confirmed as DHS Secretary on January 25, 2025, after leaving in the middle of her second term as Governor of South Dakota.

Earlier today, Noem delivered a keynote address in Nashville, Tennessee where she spoke about the importance of cooperation between DHS and local law enforcement. She was not asked any questions about her departure during the appearance.

In recent weeks Noem also appeared before both the House and Senate Judiciary Committees in Washington where lawmakers questioned her about her tenure leading the Department of Homeland Security, particularly her leadership of Immigration and Customs Enforcement.

In a post on X, Noem thanked Trump for her new role and praised DHS’ “historic accomplishments.”

During testimony before the House on March 4, lawmakers offered sharply different assessments of her record. Republican Congressman Jim Jordan of Ohio pointed to arrest and deportation numbers and described Noem’s performance at DHS as “amazing.” Democratic Congresswoman Pramila Jayapal of Washington said Noem should resign, be impeached, or be fired.

Former MMA fighter, Senator Markwayne Mullin is now expected to take over leadership of DHS as the administration reshapes key national security roles. Senator Fetterman has already expressed his support for him.
