The Senate voted late Monday night, March 23, to confirm Oklahoma Republican Sen. Markwayne Mullin as the next secretary of the Department of Homeland Security (DHS), handing President Donald Trump a key ally to lead the embattled agency amid deep dysfunction and political tension.
The final tally was 54-45, with Mullin himself registering a vote in favor as senators wrapped up a long day on the floor.
Sen. John Fetterman of Pennsylvania and Sen. Martin Heinrich of New Mexico, both Democrats, crossed party lines to support the nomination. Progressives quickly and strongly criticized them, saying they were giving Trump another tool to enforce immigration laws harshly.
Mullin, a 48-year-old former mixed martial arts fighter and businessman with no prior homeland security experience, steps into the role as DHS wrestles with a partial government shutdown now in its second month.
The funding standoff has left thousands of Transportation Security Administration(TSA) officers working without pay, causing chaotic airport delays and forcing the deployment of ICE agents to help screen passengers at major hubs.

Trump tapped Mullin earlier this month after abruptly removing Kristi Noem, whose short and stormy tenure as DHS chief ended amid mounting controversies.
Noem encountered criticism over a $220 million ad campaign that prominently featured her promoting the administration’s mass deportation push, including footage of her on horseback at Mount Rushmore.
Lawmakers from both parties questioned the contracts awarded to firms with ties to Trump operatives, and Noem drew fire for her department’s response to fatal shootings involving federal agents in Minnesota.
In his confirmation hearing, Mullin pledged to bring stability to an agency that has been in the headlines for all the wrong reasons.
“My goal in six months is that we’re not the lead story every single day,” he told senators as quoted by BBC. Securing the border, improving operations, and boosting the spirits of those on the front lines were all points he stressed.
Fetterman defended his “aye” vote by citing his working relationship with Mullin and the immediate need to fully reopen DHS.
“We need a leader at DHS. We must reopen DHS,” he said in a statement. Heinrich cited similar concerns about restoring order after what he called Noem’s “lawlessness” at the department. Both senators had previously called for Noem’s ouster.
Fear of Mullin Supporting Trump’s Hard-Line Immigration Agenda
Democrats largely lined up against Mullin, arguing that his lack of appropriate experience and close association with Trump’s hard-line immigration agenda make him unfit for the job.
Progressive groups labelled the confirmation a betrayal, with some online reactions calling Fetterman and Heinrich “sellouts” who enabled what they fear will be an escalation in deportations and interior enforcement.
Republicans cheered the outcome, viewing Mullin as a steady hand who can execute the president’s vision without the personal drama that dogged Noem.
Mullin’s path to confirmation was relatively smooth once it reached the full Senate, following a committee vote that also relied on Fetterman’s support.
The Oklahoma senator is known for his honest, unconventional approach to making laws, which doesn’t always fit with the way things are done in the Capitol.
This could prove beneficial, perhaps enabling him to guide the legislative process more easily, or it could lead to complications of its own.

The partial government shutdown continues, and the TSA is struggling with staffing shortages. This has resulted in longer, more unpredictable security lines, much to the dismay of travelers.
The administration has already begun shifting ICE personnel to airports, a stopgap measure that has drawn mixed reactions from unions and airport officials.
Immigrant rights advocates expressed alarm at Mullin’s arrival, predicting tighter policies and fewer checks on enforcement actions.
Mullin is expected to be sworn in quickly and get to work tackling the urgent operational crises while advancing broader border security goals.
Americans are expecting him to deliver the stability he promised and quiet the daily controversies, which remains to be seen in a department that has rarely been out of the spotlight since Trump returned to the White House.
