Kristi Noem Fired | The Real Story Behind Her Shocking Ouster as DHS Secretary
She rode horses in front of Mount Rushmore. She made headlines almost every week. And then, on March 5, 2026, it all came crashing down.
President Trump fired Homeland Security Secretary Kristi Noem and announced that Oklahoma Senator Markwayne Mullin would replace her. It was sudden. It was messy. And honestly? For many people watching from the inside, it wasn’t exactly a surprise.
So what really happened? Why is Kristi Noem fired — and why now? Let’s break it all down, without the spin.
Who Is Kristi Noem?
Before she became the face of America’s immigration crackdown, Kristi Noem was the governor of South Dakota. She had political star power, a strong public image, and a loyal base. When Trump nominated her to lead the Department of Homeland Security (DHS) in his second term, it felt like a natural next step for her career.
After her confirmation, she quickly became the face of the administration’s immigration agenda — making multimillion-dollar ads urging people to self-deport, conducting press conferences across the U.S. touting deportation numbers, and making international visits to promote Trump’s vision.
On paper, it sounded like a powerful role. In reality, the cracks started showing almost immediately.
Why Is Kristi Noem Fired? The Full Breakdown
There wasn’t just one reason. It was a slow, painful accumulation of controversies, missteps, and lost trust — until finally, the weight of it all became too much.
1. The $220 Million Ad Campaign — Starring Herself
This is the one that really broke things open.
Lawmakers questioned Noem about the $200 million ad campaign she oversaw that urged anyone in the U.S. illegally to self-deport. The campaign, conducted mostly in English, prominently featured Noem herself.
Think about that for a second. Taxpayer money. Hundreds of millions of dollars. And the ads kept showing her face.
Republican Senator John Kennedy confronted Noem about the advertising campaign, pointing out that contracts were often awarded through no-bid deals, with one company formed just 11 days before it was selected.
Then came the moment that sealed her fate. During the hearing, Noem claimed Trump had personally approved the spending. Kennedy later told reporters that this made the president “mad as a murder hornet” when the two spoke later that evening. Trump fired her the very next day.
2. The Minneapolis Immigration Crackdown
Minneapolis was a breaking point. Trump advisers said federal agents ended up fatally shooting two U.S. citizens during the operation — and the administration felt blindsided by the backlash.
Noem also bore responsibility for the hyper-aggressive approach of ICE in Minneapolis, which led to innocent Americans being removed from their cars and homes. Many of the agents involved had been hired after ICE slashed training requirements for new recruits.
3. FEMA Failures and Disaster Relief Delays
While immigration enforcement was dominating headlines, something else was quietly going wrong: disaster relief wasn’t getting to the people who needed it.
Under Noem’s leadership, DHS implemented a policy requiring her personal sign-off on every DHS contract, grant, or disaster award over $100,000 — creating a long backlog of pending FEMA awards, including over $500 million meant to help communities recover from the LA wildfires.
People waiting to rebuild their homes. Schools waiting to reopen. And the money was just sitting there, held up by a bureaucratic bottleneck that Noem herself had created.
4. The Corey Lewandowski Controversy
There’s no polite way to say this: rumors about Noem’s relationship with DHS aide Corey Lewandowski had been circulating for months.
Under oath, Noem refused to deny an affair with Lewandowski, her de facto chief of staff. That moment in front of the cameras reportedly became the final straw for Trump.
Noem’s non-answer about whether she had “sexual relations” with Lewandowski during a House hearing was reportedly the deciding factor in Trump’s decision to replace her.
5. Luxury Jets and a Boeing 737 with a Bar
Because why not add a private jet scandal to the mix?
Noem drew scrutiny for spending deportation funds to lease a Boeing Business Jet 737 — complete with a bedroom and a bar onboard — which was unlike any aircraft used for deportation flights. Noem and Lewandowski then lent the jet to First Lady Melania Trump, seemingly as a way to protect themselves from criticism.
As one administration official put it, they thought using the First Lady’s name would make them “bulletproof.” It didn’t.
The Breaking Point: A Week of Brutal Hearings
The final blow came after two humiliating appearances before House and Senate committees, where Noem faced bipartisan questions about alleged mismanagement, self-promotion at taxpayer expense, and the rumored affair.
Republican Senator Thom Tillis summed up the mood bluntly: “Quality matters, not quantity — and what we’ve seen is a disaster under your leadership.”
Even within her own party, the walls were closing in.
How Was She Fired?
In true Trump fashion, it happened fast and without warning.
Trump fired Noem via social media while she was actively giving a press conference — simultaneously announcing that she would be given the title of “Special Envoy for the Shield of the Americas” as a kind of parting gift.
Despite the decision, Noem went ahead with a previously scheduled speech in Nashville and made no mention of her dismissal.
Who Replaces Kristi Noem?
Trump tapped Senator Markwayne Mullin of Oklahoma to take over as DHS Secretary, with the transition set for March 31, 2026. Trump’s affection for Mullin reportedly stems largely from his TV presence — the president had frequently called Mullin after combative cable news interviews to praise him.
Mullin told reporters he found out about the nomination barely moments before it was publicly announced — he hadn’t even had a chance to call his wife yet.
What People Are Saying
The reactions have been across the board.
An administration official told NBC News that Trump fired Noem due to “a culmination of her many unfortunate leadership failures,” adding that “Kristi’s drama sadly overshadowed and distracted from the administration’s extremely popular immigration agenda.”
An adviser who spoke with Trump put it more bluntly: “She burnt up a ton of goodwill. It was everywhere. It was everything.”
Even Fox News didn’t hold back. One Fox commentator wrote that Noem was “an utter, complete, total catastrophe” whose tenure at DHS was “little more than a self-promoting crusade.”
The Bottom Line
The story of why Kristi Noem is fired isn’t really one story — it’s dozens of smaller ones that piled up over 13 months. A mismanaged agency. Taxpayer money spent on vanity ads. Deadly immigration operations. Stalled disaster relief. Personal scandals. And ultimately, a congressional hearing where she said the wrong thing to the wrong senator at the wrong time.
Noem became the first Cabinet secretary to leave her post in Trump’s second term and the circumstances of her exit say as much about the chaos inside DHS as they do about her own leadership.
She came in with enormous political potential. She’s leaving with a new title that most people have never heard of, and a legacy that will be debated for years.
