Trump taps Sen. Markwayne Mullin to lead DHS after removing Kristi Noem

Kristi Noem was ousted as Secretary of Homeland Security on Thursday, ending a turbulent 13-month tenure marked by record enforcement numbers and a series of self-inflicted wounds that ultimately cost her the job. President Donald Trump announced on Truth Social that he will nominate Sen. Markwayne Mullin, R-Okla., to replace her, effective March 31.

Noem won't leave the administration entirely. Trump said she will become Special Envoy for The Shield of the Americas, a new Western Hemisphere security initiative set to be announced Saturday in Doral, Florida.

"The current Secretary, Kristi Noem, who has served us well, and has had numerous and spectacular results (especially on the Border!), will be moving to be Special Envoy for The Shield of the Americas, our new Security Initiative in the Western Hemisphere we are announcing on Saturday in Doral, Florida."

The framing was gracious. The reality was not. Reports surfaced Thursday that Trump was furious with Noem, and a source familiar with the situation told Fox News it bluntly: "It was a combination of her many unfortunate leadership failures."

The Numbers Were Real. The Problems Were Too.

On paper, Noem's DHS compiled a record that any conservative would celebrate, Fox News reported. Under her watch, the department oversaw more than half a million pounds of illegal drugs interdicted, roughly 670,000 removals of illegal immigrants, and more than 2 million reported self-deportations in 2025. Those are staggering reversals from the open-border chaos permitted under her predecessor, Alejandro Mayorkas, during the Biden administration.

Noem herself rattled off the accomplishments in her first official statement on X following her departure:

"We have made historic accomplishments at the Department of Homeland Security to make America safe again: we delivered the MOST secure border in American history, 3 million illegal aliens have left the U.S., we have located 145,000 children, FEMA delivered disaster relief at a 100% faster rate, we ushered in the golden age of travel, saved the American taxpayer $13 billion and revitalized the U.S. Coast Guard."

None of that was enough to save her. A taxpayer-funded ad campaign drew bipartisan fire in bicameral Judiciary Committee hearings this week. A White House official confirmed to Fox News that Trump did not know about the ad and did not approve it. Then came the Minnesota operation, where U.S. Border Patrol Cmdr. Gregory Bovino, a DHS subordinate, was replaced in the Twin Cities by border czar Tom Homan. The cumulative effect was an agency head who delivered results but generated distractions the White House could no longer afford.

Wednesday's Hearing Was the Final Act

If there was a single moment that crystallized the end, it was Wednesday's House hearing. What should have been a straightforward oversight session devolved into something uglier when Rep. Sydney Kamlager-Dove, D-Calif., questioned Noem over rumors of an affair with DHS "special government employee" Corey Lewandowski, the longtime Trump aide and top figure in Trump's 2016 campaign. Kamlager-Dove asked directly whether Noem had "sexual relations with Corey Lewandowski," while slamming him as a "failed campaign manager."

Noem called the line of questioning "offensive" and said she was "shocked that we're going down and peddling this tabloid garbage in this committee today." Her husband, Bryon Noem, sat just feet behind her.

Rep. Jared Moskowitz, D-Fla., followed up, pressing Noem on Lewandowski while wearing a "Justice for Cricket pin," a reference designed to needle rather than inform. Moskowitz told Noem he thought she needed to "say the word 'no' into the record so that you can clear that up."

Noem fired back at the committee Democrats with visible anger:

"The socialist, liberal left: you go off and you attack conservative women and you say that we're either stupid or we're sluts. That's what you do. And I will tell you sir... I am neither of those."

There's a pattern here that transcends Noem. Democratic committee members routinely use oversight hearings not to conduct oversight but to manufacture viral moments. The questions about Lewandowski had nothing to do with border security, FEMA response times, or drug interdiction. They existed to humiliate. When Rep. Eric Swalwell pressed her on the ad campaign and contract, that was at least within the bounds of legitimate inquiry. The affair questioning was not.

But the hearing also exposed Noem's weakness: she couldn't stay above it. A disciplined cabinet secretary absorbs the hit and redirects to policy. Noem engaged on their terms, and the spectacle overtook the substance.

Mullin Steps Into a Running Operation

Markwayne Mullin did not see this coming. Caught dashing to vote for DHS funding, which ultimately failed again, the Oklahoma senator was sneaking through the back of the Senate when the news broke. He eventually held court on the steps outside the upper chamber and offered a disarmingly honest reaction:

"I've got to be honest with you, I wasn't expecting the call today, but I am super excited. And I'm more excited about just getting ready to get started."

Asked about specifics, Mullin acknowledged he and the president still needed to get on the same page. His first instinct, he said, was that he needed to talk to his wife.

Trump's statement on the nomination emphasized Mullin's background as the only Native American in the Senate, the first in decades since Sen. Ben Nighthorse Campbell of Colorado. But the operational case for Mullin is straightforward: he's a loyalist with energy, he doesn't carry Noem's baggage, and the enforcement infrastructure is already built. The border apparatus doesn't need a visionary right now. It needs a manager who won't become the story.

Deputy Secretary Troy Edgar, a Navy veteran and former mayor of Los Alamitos, California, sits in the line of succession and will likely serve as at least a temporary bridge before Mullin is confirmed.

The Left's Circus Continues Regardless

The Democratic response to Noem's tenure, and to immigration enforcement broadly, has been unserious in a way that should concern anyone who believes in functional opposition. When 2026 midterm candidate David Trone of Maryland filmed a protest ad outside a Williamsport compound recently purchased for use as a detention facility, he accused DHS of "executing people in the streets." No underlying event was specified. No evidence was cited. The accusation simply existed, designed to be clipped and shared.

This is where the left finds itself on immigration: unable to defend the Biden-era status quo, unwilling to credit enforcement results, and reduced to theatrical accusations that collapse under the slightest scrutiny. California Gov. Gavin Newsom and Minnesota Gov. Tim Walz have positioned themselves as high-profile critics, but criticism without a coherent alternative is just noise.

The enforcement machine Noem built, whatever her personal shortcomings, produced numbers the left cannot wish away:

• More than half a million pounds of illegal drugs seized
• Roughly 670,000 removals of illegal immigrants
• Over 2 million self-deportations in 2025
• 145,000 missing children located

Those are not talking points. Those are outcomes. The next DHS secretary inherits them.

What Comes Next

Noem moves to a role where she will work alongside Secretary of State Marco Rubio and Secretary of War Pete Hegseth on dismantling cartel networks across the Western Hemisphere. Whether the Special Envoy position carries real authority or serves as a graceful exit ramp remains to be seen. Noem, for her part, framed it as a promotion:

"The western hemisphere is absolutely critical for U.S. security. In this new role, I will be able to build on the partnerships and national security expertise, I forged over the last 13 months as Secretary of Homeland Security."

Mullin, if confirmed, takes over an agency that has been transformed from Mayorkas-era dysfunction into the most aggressive enforcement operation in a generation. The border is more secure than it has been in years. The deportation pipeline is functioning. The political headwinds are real but manageable for someone who avoids stepping on rakes.

The lesson of Noem's tenure is simple and old: in Washington, results matter, but so does execution. You can secure the border and still lose your job if you hand your enemies the ammunition. Mullin now gets the chance to prove that competence and discipline can coexist in the same building.
