President Donald Trump made one of his biggest personnel moves of his second term on Thursday, March 5, 2026, removing Kristi Noem from her role as Secretary of Homeland Security and handing her a brand-new assignment. The announcement, made via Truth Social, marked the end of a turbulent 13-month run at one of the most high-profile departments in the federal government. For anyone following the Kristi Noem new position with Trump story closely, the details behind this shake-up go far deeper than a simple job change.
Trump announced that Noem would step down from DHS effective March 31, 2026, and take on the title of Special Envoy for The Shield of the Americas — a Western Hemisphere security initiative the administration plans to formally unveil at a weekend event in Doral, Florida.

The New Role: What Is the Shield of the Americas?
The Shield of the Americas is described as a new regional security initiative focused on the Western Hemisphere. Very few details about its scope, budget, or authority have been made public so far, with the administration saving its full rollout for the Doral announcement.
In her response to the news, Noem framed the appointment as a natural continuation of her work at DHS. She said the role would allow her to build on the partnerships and national security expertise she developed over her time leading the department. She also emphasized that the Western Hemisphere is critical to U.S. national security and that she looks forward to working closely with the Secretaries of State and Defense to dismantle cartels that have funneled drugs into the country.
Whether the position carries real institutional weight — or serves as a dignified off-ramp after a stormy tenure — remains to be seen. The lack of detail around staffing, funding, and direct authority will be closely watched by both allies and critics in the weeks ahead.
What Led to Noem’s Removal?
Noem’s exit did not come out of nowhere. Frustrations inside the White House had been building for months, and they reached a breaking point following two days of contentious congressional hearings on Tuesday and Wednesday of this week.
At the center of the controversy was a $220 million advertising campaign that Noem oversaw at DHS — a nationwide push urging people living in the country illegally to self-deport. The ads featured Noem prominently, and the contract for the campaign was awarded to firms with ties to Republican political operatives, bypassing standard competitive bidding procedures. Lawmakers from both parties pushed back hard on the spending and the contracting process during the hearings.
The situation worsened when Noem testified that President Trump had personally approved the campaign in advance. Shortly afterward, Trump told reporters he had never known anything about it. That direct public contradiction between Noem and the president effectively ended whatever trust remained between them and the White House.
Beyond the ad controversy, Republican senators who had previously supported Noem declined to express continued confidence in her leadership. Senator Thom Tillis of North Carolina called her tenure a disaster, saying he had been disappointed time after time. Even close Trump allies like Senator Lindsey Graham offered only cautious, noncommittal responses when asked whether they still backed her.
The Minneapolis Crisis and Other Flashpoints
The ad campaign was not the only issue haunting Noem’s final weeks at DHS. Earlier this year, two American citizens — Renee Good and Alex Pretti — were shot and killed by federal immigration agents during enforcement operations in Minneapolis. The incident drew national attention and furious bipartisan criticism.
Noem’s handling of the aftermath damaged her standing both on Capitol Hill and inside the West Wing. White House border czar Tom Homan was dispatched to Minneapolis to take over the situation, a move widely interpreted as a public rebuke of Noem’s leadership. Reports of a long-running feud between Homan and Noem — and that the two rarely communicated — added to the picture of dysfunction inside DHS.
Noem also faced criticism over the department’s handling of national disaster relief, including responses to major weather events and hurricane damage.
Who Is Taking Over at DHS?
Trump announced that Oklahoma Senator Markwayne Mullin will become the next Secretary of Homeland Security, effective March 31, 2026. The Senate will need to hold a confirmation vote before Mullin can officially take over the role.
Mullin, a first-term senator and former House member who represented Oklahoma for a decade before moving to the Senate, is known as a fierce defender of Trump’s agenda. Trump highlighted Mullin’s background as a former professional MMA fighter, his Cherokee Nation heritage, and his television presence — noting that he has frequently praised Mullin following combative cable news appearances.
If confirmed, Mullin will oversee an enormous portfolio. The DHS secretary is responsible for the Coast Guard, the Federal Emergency Management Agency, Immigration and Customs Enforcement, the Secret Service, Transportation Security Administration, and a broad range of cybersecurity and counterterrorism functions.
A First-Term Cabinet Departure — and What It Signals
Noem becomes the first Cabinet secretary to leave the Trump administration in his second term. Trump’s second-term approach has been notably different from his first, when he went through five DHS secretaries — including three acting ones — and was known for abrupt firings. This time, he has opted to reassign Noem into a new role rather than simply remove her, a pattern that reflects a more managed style of handling departures.
During her time at DHS, Noem’s department seized over 617,000 pounds of illicit drugs — including more than 10,000 pounds of fentanyl — representing an 8 percent increase over the prior year. She was also at the forefront of Trump’s mass deportation operations and oversaw the implementation of a landmark $65 billion border security bill.
But those accomplishments were repeatedly buried under controversy, and White House officials privately acknowledged that her personal drama had overshadowed the administration’s immigration agenda — one they described as extremely popular with their base.
Close Noem aide Corey Lewandowski, who also drew scrutiny from lawmakers over his advisory role at DHS and questions about his authority to approve grants and contracts, is expected to leave the department alongside her.
What Comes Next
The next few weeks will be critical. DHS is currently operating under a partial government shutdown, with congressional funding for the department having lapsed. The transition timeline — with Mullin not officially taking over until March 31 — leaves the department in an extended period of uncertainty.
Meanwhile, the Doral summit this weekend is expected to define what the Shield of the Americas will actually look like in practice. Regional security cooperation, combating cartel activity, countering Chinese influence in Latin America, and managing migration flows across the hemisphere are all expected to be on the agenda.
For Noem, the new title represents either a meaningful second act or a quiet political consolation prize — and which one it turns out to be will likely depend on how much real authority and White House backing the role receives going forward.
