Mullin pledges to ‘protect everybody’ as he takes over Department of Homeland Security

WASHINGTON (States Newsroom) — President Donald Trump hailed his new Homeland Security head, former U.S. Sen. Markwayne Mullin, as “strong, professional and fair” during an Oval Office swearing-in ceremony Tuesday.

Mullin, who until Monday was one of Oklahoma’s Republican senators, takes the reins at the Department of Homeland Security amid a weekslong partial shutdown in the aftermath of two high-profile fatal shootings of U.S. citizens by two departmental agencies.

Mullin, accompanied by family at the Oval Office ceremony, described his swearing-in as “surreal” and “humbling” during brief remarks after Attorney General Pam Bondi administered his oath of office.

“I made this very clear that I don’t care what color your state is. I don’t care if you’re red or you’re blue. At the end of the day, my job is to be secretary of Homeland and to protect everybody the same. And we will do that. I’ll fight every single day,” Mullin said.

The partial shutdown has snarled major airports nationwide as thousands of Transportation Security Administration personnel, part of DHS, have quit or skipped work in the absence of paychecks.

Mullin said he met with many DHS employees Tuesday, noting they had been working without pay for more than a month because of “politics.”

Former fighter

Trump praised Mullin at Tuesday’s ceremony.

“I have no doubt that as he takes the helm of DHS, Markwayne will fight for Homeland Security, the United States and securing the country and making it really strong and the way it should be,” Trump said. “Our country’s come a long way in the last year.”

In rising to the role, Mullin became the first member of the Cherokee Nation to serve in the president’s Cabinet, a fact Trump said he “didn’t know.”

Mullin, an award-winning wrestler and former professional mixed martial arts fighter, began his Senate term in 2023. Until being elected as senator, he represented Oklahoma’s 2nd Congressional District starting in 2013.

Mullin resigned from the U.S. Senate Monday evening following the body’s confirmation of his appointment in a 54-45 vote.

The former senator, who will be tasked with leading a department of 260,000 employees, has not sat on a committee that handles policy for Homeland Security.

Alan Armstrong, a Tulsa businessman, was sworn in Tuesday to replace Mullin in the Senate.

Department in turmoil

Mullin replaces former Secretary Kristi Noem who, since Trump’s second term began, oversaw the president’s mass deportation crackdown and publicly flaunted her role in ad campaigns and public appearances — including being photographed while touring a notorious mega-prison in El Salvador where the U.S. deported hundreds of migrants against a judge’s order.

Noem notably immediately defended two fatal shootings by department personnel in Minneapolis when Immigration and Customs Enforcement agents killed 37-year-old Renee Good on Jan. 7, and Customs and Border Patrol agents killed Alex Pretti, also 37, on Jan. 24.

Democrats have refused to fully fund DHS unless Republicans agreed to new policies for immigration enforcement — including banning face coverings on agents, mandating body camera usage and requiring judicial warrants.

“The department that Markwayne takes over today is currently shut down by radical left Democrat thugs in Congress who have blocked all funding for DHS because they’re trying to shield illegal aliens, criminals and gang members,” Trump said, incorrectly stating that all DHS funding has been blocked.

While a significant number of DHS employees, like TSA officers, have been working for weeks without pay, both ICE and Customs and Border Protection are fully funded under a new influx of cash Republicans approved in July as part of the massive tax and spending package.

Speaking to reporters following Mullin’s swearing-in, Trump declined to talk in detail about negotiations with the Senate to end the partial shutdown.

“They’re working on all of that,” he said.
