Washington — The leadership of the Department of Homeland Security is undergoing a sudden shakeup after President Donald Trump announced he intends to nominate Sen. Markwayne Mullin of Oklahoma to replace current Homeland Security Secretary Kristi Noem.
Trump said Noem will move to a new role as a special envoy tied to a broader security initiative in the Western Hemisphere, a shift that comes amid growing internal frustration inside the administration over her leadership of the sprawling federal department.
POWER SHAKEUP AT HOMELAND SECURITY
The change became public Thursday when Trump posted on Truth Social that he would nominate Mullin to the Cabinet role while shifting Noem to a diplomatic assignment connected to regional security cooperation.
In the same message, Trump praised Noem’s record leading the department.
“has served us well, and has had numerous and spectacular results (especially on the Border!).”
Trump also revealed the new assignment awaiting her.
Noem will become a special envoy for the “our new Security Initiative in the Western Hemisphere we are announcing on Saturday” during a summit with Latin American leaders in Florida.
“I thank Kristi for her service at ‘Homeland,’” Trump added.
The timing caught many observers off guard. Trump’s announcement was posted roughly 20 minutes before Noem began speaking at the Sergeant Benevolent Association Major Cities Conference in Tennessee. During prepared remarks at the event, she did not reference the change.
MARKET-STYLE POLITICAL PRESSURE BUILDS
Behind the scenes, frustration with Noem had been building for months among senior figures in the administration and on Capitol Hill.
Senior administration officials had privately urged Trump to replace her in recent days, according to multiple Republicans familiar with the discussions and a person close to the White House.
Those conversations reportedly reached the highest levels of the administration, including chief of staff Susie Wiles. Border czar Tom Homan, who has often clashed with Noem, was described as a key figure pushing for the change.
The scrutiny intensified after Noem’s testimony before the Senate Judiciary Committee earlier this week. According to people familiar with the president’s private conversations, the hearing triggered fresh frustration inside the White House.
During the hearing, Noem was questioned about a controversial advertising campaign that cost hundreds of millions of dollars and prominently featured her in the messaging.
She told senators the president approved the campaign. That claim reportedly became a major sticking point inside the administration.
“POTUS did not sign off on a $220 million dollar ad campaign,” a White House official said. “Absolutely not.”
The ads had already been a sore subject internally, with some officials worried the campaign fed perceptions that Noem was positioning herself for a future political run.
IMMIGRATION RESULTS — AND POLITICAL FALLOUT
Despite the growing tension, Noem’s tenure was closely tied to the administration’s aggressive immigration enforcement strategy.
Her leadership coincided with sweeping deportation operations and a broader crackdown on illegal border crossings that supporters within the administration said produced dramatic results.
Republican allies have pointed to sharp declines in illegal crossings and record drug interdictions as evidence that the policy shift worked.
But the political backlash grew after a chaotic enforcement surge in Minneapolis earlier this year. Federal agents killed two U.S. citizens in January, sparking intense criticism and public scrutiny.
Some Republicans privately faulted Noem for rushing to television appearances immediately after the incident, arguing that her approach undermined confidence in the ongoing investigation.
The fallout fueled calls from some GOP lawmakers for her resignation and intensified debate inside the administration about whether the department needed new leadership.
SCANDALS, CONTRACT QUESTIONS AND INTERNAL STRAIN
The pressure was compounded by questions surrounding spending decisions and internal management of the department.
Lawmakers grilled Noem over the advertising campaign during congressional hearings, while critics also focused on the role of her special adviser Corey Lewandowski.
Lewandowski, a longtime Trump political figure, has reportedly held significant influence over high-level DHS decisions, including approval of contracts exceeding $100,000.
Officials have also raised questions about how his role is structured within the agency. As a special governmental employee, the position is typically limited to 130 days per year of unpaid work.
Administration officials said Lewandowski’s involvement in key decisions has also drawn scrutiny, including DHS’s aborted attempt to shut down TSA PreCheck as part of a broader political funding strategy.
“All the contracts and other scandals are facing recurring scrutiny,” one administration official said. “No one is talking about the most secure border ever. Just the shitshow that is Noem and Corey.”
MULLIN STEPS INTO THE SPOTLIGHT
Trump’s pick to replace Noem is Sen. Markwayne Mullin, a Republican from Oklahoma and longtime ally of the president.
The nomination still requires Senate confirmation, and it remains unclear whether lawmakers could move quickly enough to meet Trump’s apparent goal of having Mullin installed by March 31.
Mullin struck a friendly tone shortly after the announcement.
“The president and I are good friends,” Mullin told reporters. “We look forward to working closer with the White House. Obviously, I’m gonna be over there a lot more.”
For now, the leadership shift marks one of the most significant changes inside the administration’s national security apparatus since Trump returned to office — and it underscores how quickly political pressure can reshape even the highest levels of government power.
