Trump Names Markwayne Mullin as New Homeland Security Secretary
US President Donald Trump has announced that Oklahoma Senator Markwayne Mullin will be his new Secretary of the United States Department of Homeland Security, replacing embattled former chief Kristi Noem.
Mullin, a first-term senator and former mixed martial arts fighter, has been a strong supporter of Trump and his policies since arriving in Washington.
Mullin will become the second Homeland Security secretary during Trump’s second presidential administration.
Mullin Promises to Focus on Homeland Security
Speaking to reporters outside the U.S. Capitol following the announcement, Mullin said his main priority would be protecting the United States.
“Yes, I’m a Republican and yes, I’m conservative,” Mullin said. “But my focus once I take this role is to keep the homeland secure and enforce the laws passed by Congress.”
The Oklahoma senator has consistently supported strong immigration enforcement, a key pillar of Trump’s political agenda. He has frequently praised federal immigration authorities, particularly U.S. Immigration and Customs Enforcement, for their work detaining undocumented immigrants.
Criticism of Government Shutdown and Immigration Debate
Mullin has also been outspoken about the ongoing partial U.S. government shutdown that temporarily affected funding for the Department of Homeland Security.
In a recent interview with CNN, Mullin accused Democrats of using the funding fight as political theater.
“What is happening right now is political theatre,” Mullin said. “Shutting down DHS doesn’t stop ICE from doing its job.”
Controversies Facing the Homeland Security Department
If confirmed, Mullin will inherit an agency facing growing scrutiny, particularly following a controversial immigration enforcement operation in Minnesota that resulted in the deaths of two U.S. citizens.
The deaths sparked national debate about the tactics used by federal immigration agents. Mullin has previously defended law enforcement officers, stating that obstructing federal officers is a serious crime and that immigration agents are performing a difficult job.
“These patriots are doing a difficult job and facing threats,” Mullin wrote on social media after the shooting of Minneapolis resident Alex Pretti.

A Fiery Personality in the Senate
Mullin has gained national attention for his outspoken and confrontational style.
One of the most talked-about moments of his Senate career occurred during a heated 2023 hearing of the United States Senate Committee on Health, Education, Labor and Pensions.
During the hearing, Mullin confronted Sean O’Brien, leader of the powerful International Brotherhood of Teamsters, after O’Brien criticized him on social media.
“You want to run your mouth, we can be two consenting adults — we can finish it here,” Mullin said before standing up and appearing ready to fight.
Another senator quickly intervened and ordered Mullin to sit down, preventing the confrontation from escalating further.

Before entering politics, Mullin had a unique career path.
He previously competed as a mixed martial arts fighter and later worked alongside his wife to grow a successful family plumbing business. According to his official biography, the couple built the business over two decades while raising their six children.

Her department faced criticism over:

Noem also faced intense questioning during congressional hearings, including criticism from members of her own party.

The Department of Homeland Security oversees border protection, immigration enforcement, counterterrorism operations, and disaster response.
His confirmation hearing is expected to focus heavily on immigration policy, federal law enforcement tactics, and the future direction of DHS.
